HAP602 Harvard University Spouse Depression Case Study 2 Analysis
Use this case study in combination with the Case Study 2 – AA Spouse Depression.xlsx A study in 2005 was conducted to determine whether there was a difference in the depression of women and men who were participating in Alcoholics Anonymous program as well as whether the presence of their spouses at the meetings had a relationship on their depression score. One-hundred-ninety-six men and women participated in the study, and their depression scores after 30 days and 180 days were captured using a depression inventory on which lower scores represented lesser depression. The score range on the instrument is 3 to 24. The data are contained in the file “Case Study 2 - AA Spouse Depression.csv.” You will perform a set of analyses on the data with the file, and then interpret the results to indicate your findings. The column Spouse Present indicates whether the participant was enrolled in an AA program that encouraged spouses to attend (1) or did not allow others except the participant to attend meetings (called closed meetings). In addition, the age and urban or rural residence of the participant is shown. All participants are married whether their spouse attended or not. 1) Prepare a table of the data using the following template. Sex Mean Depression Score, 30 days (sd) Mean Depression Score, 180 days (sd) Mean Age, (sd) Male Attended with spouse Attended without spouse Female Attended with spouse Attended without spouse Based on this information alone, what conclusions can you state? 2) Which group had the most variation in depression scores at 30 days, men or women? Did this change at 180 days?

Course Project - Phase 5, statistics homework help
This week you will submit Phase 5, the final phase, of your course project. For Phase 5 of your course project, you will want to review your instructor's feedback from your Phase 4 submission and 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 make your final submission for the course project. Below is a summary of the expectations for Phase 5 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. Mean Median Mode Midrange Range Variance Standard Deviation Discuss 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. 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? 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. Conclusion Recap your ideas by summarizing the information presented in context of your chosen scenario. Please be sure to show all of your work and use the Equation Editor to format your equations.

MTH410 Colorado State University Module 5 Finer Suit Company Report
Finer Suit Company sells suits in the US and the European Union. The company monitors its suit sales by collecting randomly chosen data from store locations throughout the US. They record list price (in dollars), sale price (in dollars), and number of days it takes to sell each suit. Data was collected from 200 suits sold in the US and 200 in the EU region. The complete data set is in the file named Suits.Managerial ReportPrepare a report (see Module folder) that summarizes your assessment of the nature of the suit market in each region. Be sure to include the following seven items in your report.
Descriptive statistics (mean, median, range, standard deviation, and coefficient of variation) to summarize each of the three variables for the all US suits. Use z-scores to determine if there any outliers in the data set for any of the three variables. If there are any outliers in any category, please list them and state for which category they are an outlier. If a result is an outlier, state whether it is below or above the mean.
Descriptive statistics (mean, median, range, standard deviation and coefficient of variation) to summarize each of the three variables for the all EU suits. Use z-scores to determine if there any outliers in the data set for any of the three variables. If there are any outliers in any category, please list them and state for which category they are an outlier. If a result is an outlier, state whether it is below or above the mean.
Compare your summary results from #1 and #2. Discuss any specific statistical results that would help Finer Suits understand its business.
Develop a 99% confidence interval estimate of the population mean sales price and population mean number of days to sell for US suits. What is the Margin of error? What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.
Develop a 99% confidence interval estimate of the population mean sales price and population mean number of days to sell for EU suits. What is the Margin of error? What are the lower (or left) and upper (or right) endpoints of the confidence interval? Interpret your results.
Assume the Finer Suit Company requested estimates of the mean List Price for the US suits with a margin of error of $600 and the mean List Price of EU suits with a margin of error of $600. Using 99% confidence, how large should the sample sizes be for each?
Suppose a US suit has a list price of $1,500 and a EU suit has a list price of $1,200. What is your estimate of the final selling price (based on the percent difference for the sale and list price) and number of days required to sell each of these suits?
