Course Project - Phase 4 Classify the variables in your data set, statistics homework help
This week you will begin working on Phase 4 of your course project. For Phase 4 of your course project, you will want to review your instructor's feedback from your Phase 1, Phase 2, and Phase 3 submissions to make any necessary corrections. Remember if you have questions about the feedback to ask your instructor for assistance.Once you have made your corrections, you will compile your information from Phase 1, Phase 2, Phase 3 and your final conclusion into one submission and submit this as your rough draft for Phase 4 of the course project. Below is a summary of the expectations for Phase 4 of the course project:Introduce your scenario and data set.Provide a brief overview of the scenario you are given above and the data set that you will be analyzing.Classify the variables in your data set.Which variables are quantitative/qualitative?Which variables are discrete/continuous?Describe the level of measurement for each variable included in your data set.Discuss the importance of the Measures of Center and the Measures of Variation.What are the measures of center and why are they important?What are the measures of variation and why are they important?Calculate the measures of center and measures of variation. Interpret your results in context of the selected topic.MeanMedianModeMidrangeRangeVarianceStandard DeviantionDiscuss the importance of constructing confidence intervals for the population mean.What are confidence intervals?What is a point estimate?What is the best point estimate for the population mean? Explain.Why do we need confidence intervals?Based on your selected topic, evaluate the following:Find the best point estimate of the population mean.Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown.Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.Write a statement that correctly interprets the confidence interval in context of your selected topic.Based on your selected topic, evaluate the following:Find the best point estimate of the population mean.Construct a 99% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown.Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations.Write a statement that correctly interprets the confidence interval in context of your selected topic.Compare and contrast your findings for the 95% and 99% confidence interval.Did you notice any changes in your interval estimate? Explain.What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain.Discuss the process for hypothesis testing.Discuss the 8 steps of hypothesis testing?When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why?Perform the hypothesis test.If you selected Option 1:Original Claim: The average salary for all jobs in Minnesota is less than $65,000.Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown.Based on your selected topic, answer the following:Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim.Is the test two-tailed, left-tailed, or right-tailed? Explain.Which test statistic will you use for your hypothesis test; z-test or t-test? Explain.What is the value of the test-statistic? What is the P-value? What is the critical value?5.)What is your decision; reject the null or do not reject the null?Explain why you made your decision including the results for your p-value and the critical value.State the final conclusion in non-technical terms.ConclusionRecap your ideas by summarizing the information presented in context of your chosen scenario.g310_dataset_option1.xlsxg310_scenario_option1.docx

West Coast University Microsoft Excel Data Set Worksheet
This assignment, like subsequent assignments each week, will help you make progress toward your final project.The first step is to understand how to use Microsoft Excel to enter data that you collected on individuals. You will use the information below for this assignment.Male, age 50, HispanicMale, age 39, African AmericanFemale, age 19, European AmericanMale, age 22, Asian AmericanFemale, age 88, European AmericanFemale, age 37, HispanicFemale, age 43, Asian AmericanMale, age 72, Native AmericanMale, age 45, European AmericanFemale, age 30, African AmericanEnter the above information on the 10 imaginary research participants in Excel. Here are a few rules to keep in mind when creating a data set in Excel: The first row consists of variable names (column heading). Subsequent rows contain participants’ data. For this data set, the data you enter should only be the numbers that represent the information presented above, with the following column heading and rows of data:Column name: ID, Rows of data: 1 through 10Column name: Gender, Rows of data: Male = 1, Female = 2Column name: Age: (just type in the number)Column name: Race, Rows of data: Hispanic = 1, African American = 2, European American = 3,
Asian American = 4, Native American = 5In addition, create a codebook on the second sheet of your Excel document, so that other people who view your data set can understand what the numeric answer for different variables represent. It will look as simple as this: Gender (male = 1, female = 2)Age: number in yearsEthnicity (Hispanic = 1, African American = 2, European American = 3,
Asian American = 4, Native American = 5

continuously distributed variables, statistics homework help
You are an inventory manager working for a large online retailer. As with any retailer, inventory control is one of the critical success factors for the organization. Having too little inventory risks the loss of sales when your company is unable to fulfill an order. However, too much inventory imposes unnecessary costs on the organization. Often, one of the most important pieces of information that can be used to determine how much inventory to have on hand is the rate at which demand occurs for the product.Determine what information you would need to construct a confidence interval for the demand that will occur during a month.Analyze how the numbers of such a confidence interval might influence the level of inventory that the organization chooses to carry. Support your discussion with relevant examples, research, and rationale.
