Rasmussen College Inferential Statistics and Analytics Discussion
InstructionsYou are currently working at NCLEX Memorial Hospital in the Infectious Diseases Unit. Over the past few days, you have noticed an increase in patients admitted with a particular infectious disease. You believe that the ages of these patients play a critical role in the method used to treat the patients. You decide to speak to your manager, and together you work to use statistical analysis to look more closely at the ages of these patients.You do some research and put together a spreadsheet of the data that contains the following information:Client numberInfection disease statusAge of the patientYou are to put together a PowerPoint presentation that explains the analysis of your findings which you will submit to your manager. The presentation should contain all components of your findings. For review, the components of the report should include:Brief overview of the scenario and variables in the data setDiscussion, calculation, and interpretation of the mean, median, mode, range, standard deviation, and varianceDiscussion, construction, and interpretation of the 95% confidence intervalExplanation of the full hypothesis testConclusionThe calculations should be performed in your spreadsheet that you will also submit to your manager. You can find additional information on what to add to your PowerPoint presentation in this Word document. Use the questions in the worksheet as your guide for the contents of your presentation.For your final deliverable, submit your PowerPoint presentation and the Excel workbook showing your work.

ANOVA project
Directions: Use the following information to complete the assignment. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center. A researcher randomly assigns 33 subjects to one of three groups. Group 1 receives technical dietary information interactively from an on-line website. Group 2 receives the same information from a nurse practitioner, while Group 3 receives the information from a video tape made by the same nurse practitioner. The researcher looked at three different ratings of the presentation; difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation. In particular, the researcher is interested in whether the interactive website is superior because that is the most cost-effective way of delivering the information.

Grantham University Confidence Interval Proportion of Schools Project
Project Assignment Part 1For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet. Download it here.Using the ROI data set:For each of the 2 majors consider the ‘School Type’ column. Assuming the requirements are met, construct a 90% confidence interval for the proportion of the schools that are ‘Private’. Be sure to interpret your results.For each of the 2 majors construct a 95% confidence interval for the mean of the column ‘Annual % ROI’. Be sure to interpret your results.Project Assignment Part 2For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet. Download it here.Using the ROI data set:For each of the 2 majors test the hypothesis at the 5% significance level:The mean ‘Cost’ for a college is $160,000. Be sure to interpret your results.For Business versus Engineering majors conduct a two sample test of the hypothesis at the 10% significance level (assume the variances are not equal):The average ’30-Year ROI’ for Business majors is less than for Engineering Majors. Be sure to interpret your results.Project Assignment Part 3For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet. Download it here.Using the ROI data set:For each of the two majors:Draw the scatter diagram of Y = ‘Annual % ROI’ against X = ‘Cost’.Obtain b0 and b1 of the regression equation defined as y ̂ = b0 + b1X and the coefficient of determination (r2) from the Excel regression output. Draw the fitted regression line on the scatter diagram.Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000.Test the hypothesis: oH0: β1 = 0oHa: β1 ≠ 0Write a paragraph or more on any observations you make about the regression estimates, coefficient of determination, the plots, and the results of your hypothesis tests.Project Assignment Part 4Write a minimum 4 page report explaining the results from your analysis of the ROI of Business Majors and Engineering Majors. Use your results from each week’s assignment to make this report.This report should include:A detailed description of the data used in this analysis – specifically explain what the data in each column represents.A detailed explanation of any information learned about:School Type for each major; The Cost for each major;The 30 Year ROI for each major;The Annual % ROI for each major.Explanations should be supported with the results obtained from your work in previous weeks.Finally, answer the following questions and support your answer with your results.Does there appear to be a particular major that gives a better ROI? Why or Why not? Given that we are using statistical inference to make our conclusions, is it guaranteed that the major you choose that gave a better ROI for this sample will always have a better ROI than the other major? Explain your reasoning
