I need help with my Inferential Statistics Class it is kicking my butt
CompetencyFormulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians.Student ProfileYou are a statistician working for a drug company. A few new scientists have been hired by your company. They are experts in pharmacology, but are not experts in doing statistical studies, so you will explain to them how statistical studies are done when testing two samples for the effectiveness of a new drug. The two samples can be dependent or independent, and you will explain the difference.
Concept being Studied Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters.What to SubmitYour research and analysis should be presented on the Word document provided. All calculations should be provided on a separate Excel workbook that should be submitted to your boss as well.

Capella University Descriptive Statistics and Data Visualizations Summary
Create a descriptive statistics table and histogram for selected variables in a dataset. Write a 2-3 page narrative summary in a Word document and insert the table and histogram graphic into this document.IntroductionNote: You are strongly encouraged to complete the assessments in this course in the order they are presented.Descriptive statistics play an important role in analyzing data. It numerically summarizes key characteristics of variables. Measures of central tendency (mean, median, and mode) and dispersion (variance, standard deviation, and range) characterize the probability distribution. A histogram visualizes the distribution of numerical data indicating the number of data points that lie within a range of values. For this assessment, you will perform descriptive statistics and create a histogram for selected variables in a dataset.OverviewNote: Complete the assessments in this course in the order in which they are presented.Data Analysis SoftwareTo complete the assessments in this course, you will need to use data analysis software to complete statistical calculations, create graphs, and tabular summaries, and share your results in a Microsoft Word document. You will use Microsoft Excel and Microsoft Excel Analysis ToolPak add-in. Be aware that not all statistical calculations, graphs, and tabular summaries can be completed in this software, so you may need to do some work outside of the software.Microsoft Excel Data Analysis ToolPak Add-In for PC and MacMicrosoft Excel Analysis ToolPak Activation for PC Users: The Microsoft Excel Analysis ToolPak is a specialized Excel add-in included in the standard Microsoft Office suite. If your Excel software meets the standard Capella University Computer Requirements, you will not need to purchase this software.

The following provides an overview of the Analysis ToolPak, instructions for loading and activation and instructions on using the ToolPak to perform data analysis. Note that these instructions are for 2016 and older versions of Microsoft Excel for PC and for the 2016 version only for Mac. If you are using a different version, you may need to search Microsoft's website for the appropriate instructions.Use the Analysis ToolPak to Perform Complex Data Analysis.Preparation Download the Assessment 1 Dataset [XLSX]. The dataset contains the following variables:utilization (average number of patient days per month).satisfaction (patient satisfaction scores percentile rank).readmissions (readmission rate per month).InstructionsNursing home administration has the objectives of higher utilization, higher patient satisfaction, and lower readmissions, and they need to make a decision on whether to retain the department manager based on average performance over the past 70 months. For this assessment, create a descriptive statistics table and histogram based on the Assessment 1 Dataset. Write a narrative summary in a Word and insert the table and histogram graphic into this document. See Copy From Excel to Another Office Program for instructions. Submit both the Word document and the Excel file that shows the descriptive statistics output.Grading CriteriaThe numbered assessment instructions outlined below correspond to the grading criteria in the Descriptive Statistics and Data Visualizations Scoring Guide, so be sure to address each point. You may also want to review the performance-level descriptions for each criterion to see how your work will be assessed.Perform the appropriate descriptive statistics for selected variables in a dataset.Report descriptive statistics table with measures of central tendency and dispersion.Create a histogram that visually depicts the distribution of selected variables in a dataset.Interpret statistical results used in the data analysis.Write a narrative summary of the results that includes practical, administration-related implications of the descriptive statistics.Write a separate summary for the histogram.Write clearly and concisely, using correct grammar, mechanics, and APA formatting.Additional RequirementsYour assessment should meet the following requirements:Written communication: Write clearly, accurately, and professionally, incorporating sources appropriately.Length: 2–3 pagesResources: Not applicable.APA format: Cite your sources using current APA format.Font and font size: Times Roman, 12 point.Competencies MeasuredBy successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:Competency 2: Analyze data using computer-based programming and software.Perform the appropriate descriptive statistics for selected variables in a dataset.Competency 3: Interpret results of data analysis for value-based health care decisions, policy, or practice.Interpret statistical results used in the data analysis.Competency 4: Present results of data analysis to support a decision or recommendation.Create a histogram that visually depicts the distribution of selected variables in a dataset.Write a narrative summary of the results that includes practical, administration-related implications of the descriptive statistics.Competency 5: Communicate audience-appropriate health management content in a logically structured and concise manner, writing clearly with correct use of grammar, punctuation, spelling, and APA style.Write clearly and concisely, using correct grammar, mechanics, and APA formatting.SCORING GUIDEUse the scoring guide to understand how your assessment will be evaluated.

I need help with my Inferential Statistics Class it is kicking my butt
CompetencyFormulate and evaluate hypothesis tests for population parameters based on sample statistics using both Critical Regions and P-Values, and be able to state results in a non-technical way that can be understood by consumers of the data instead of statisticians.Student ProfileYou are a statistician working for a drug company. A few new scientists have been hired by your company. They are experts in pharmacology, but are not experts in doing statistical studies, so you will explain to them how statistical studies are done when testing two samples for the effectiveness of a new drug. The two samples can be dependent or independent, and you will explain the difference.
Concept being Studied Your focus is on hypothesis tests and confidence intervals for two populations using two samples, some of which are independent and some of which are dependent. These concepts are an extension of hypothesis testing and confidence intervals which use statistics from one sample to make conclusions about population parameters.What to SubmitYour research and analysis should be presented on the Word document provided. All calculations should be provided on a separate Excel workbook that should be submitted to your boss as well.

Capella University Descriptive Statistics and Data Visualizations Summary
Create a descriptive statistics table and histogram for selected variables in a dataset. Write a 2-3 page narrative summary in a Word document and insert the table and histogram graphic into this document.IntroductionNote: You are strongly encouraged to complete the assessments in this course in the order they are presented.Descriptive statistics play an important role in analyzing data. It numerically summarizes key characteristics of variables. Measures of central tendency (mean, median, and mode) and dispersion (variance, standard deviation, and range) characterize the probability distribution. A histogram visualizes the distribution of numerical data indicating the number of data points that lie within a range of values. For this assessment, you will perform descriptive statistics and create a histogram for selected variables in a dataset.OverviewNote: Complete the assessments in this course in the order in which they are presented.Data Analysis SoftwareTo complete the assessments in this course, you will need to use data analysis software to complete statistical calculations, create graphs, and tabular summaries, and share your results in a Microsoft Word document. You will use Microsoft Excel and Microsoft Excel Analysis ToolPak add-in. Be aware that not all statistical calculations, graphs, and tabular summaries can be completed in this software, so you may need to do some work outside of the software.Microsoft Excel Data Analysis ToolPak Add-In for PC and MacMicrosoft Excel Analysis ToolPak Activation for PC Users: The Microsoft Excel Analysis ToolPak is a specialized Excel add-in included in the standard Microsoft Office suite.

The dataset contains the following variables:utilization (average number of patient days per month).satisfaction (patient satisfaction scores percentile rank).readmissions (readmission rate per month).InstructionsNursing home administration has the objectives of higher utilization, higher patient satisfaction, and lower readmissions, and they need to make a decision on whether to retain the department manager based on average performance over the past 70 months. For this assessment, create a descriptive statistics table and histogram based on the Assessment 1 Dataset. Write a narrative summary in a Word and insert the table and histogram graphic into this document. See Copy From Excel to Another Office Program for instructions. Submit both the Word document and the Excel file that shows the descriptive statistics output.Grading CriteriaThe numbered assessment instructions outlined below correspond to the grading criteria in the Descriptive Statistics and Data Visualizations Scoring Guide, so be sure to address each point. You may also want to review the performance-level descriptions for each criterion to see how your work will be assessed.Perform the appropriate descriptive statistics for selected variables in a dataset.Report descriptive statistics table with measures of central tendency and dispersion.Create a histogram that visually depicts the distribution of selected variables in a dataset.Interpret statistical results used in the data analysis.Write a narrative summary of the results that includes practical, administration-related implications of the descriptive statistics.Write a separate summary for the histogram.Write clearly and concisely, using correct grammar, mechanics, and APA formatting.Additional RequirementsYour assessment should meet the following requirements:Written communication: Write clearly, accurately, and professionally, incorporating sources appropriately.Length: 2–3 pagesResources: Not applicable.APA format: Cite your sources using current APA format.Font and font size: Times Roman, 12 point.Competencies MeasuredBy successfully completing this assessment, you will demonstrate your proficiency in the following course competencies and assessment criteria:Competency 2: Analyze data using computer-based programming and software.Perform the appropriate descriptive statistics for selected variables in a dataset.Competency 3: Interpret results of data analysis for value-based health care decisions, policy, or practice.Interpret statistical results used in the data analysis.Competency 4: Present results of data analysis to support a decision or recommendation.Create a histogram that visually depicts the distribution of selected variables in a dataset.Write a narrative summary of the results that includes practical, administration-related implications of the descriptive statistics.Competency 5: Communicate audience-appropriate health management content in a logically structured and concise manner, writing clearly with correct use of grammar, punctuation, spelling, and APA style.Write clearly and concisely, using correct grammar, mechanics, and APA formatting.SCORING GUIDEUse the scoring guide to understand how your assessment will be evaluated.
