QUESTION
Action ItemsData Analysis Inference ProjectPurposeTo assess your ability to: define and apply basic terms commonly used in statistics.
- Draw inferences from the data. For this part you will need to use both the male and female data for your variable. Complete the following:Use the sample data to construct a 95% confidence interval for the mean of all males and interpret it in the context of the problem.
- Use the sample data to construct a 95% confidence interval for the mean of all females and interpret it in the context of the problem.
- Use the sample data to construct a 95% confidence interval for the difference of means of all males and all females. Explain if there is a difference between the means of males and females.
- Conduct a hypothesis test with 0.05 significance to test if the mean of all males is different from the mean of all females. Show all steps of hypothesis testing in your report including interpretation of the results.
- Discuss if the results of the hypothesis test are different from the results of the confidence interval for the difference of two means.
- a formal paper incorporating and explaining the results from the previous parts.
- In your report:Describe the data set and the variable you worked with.
- Give a summary of the analysis you have done in Part 1 of this project:Give the measures of the center and explain which measure best fits this data set.
- Give the measures of variation.
- Include the boxplot (done by using MS Word) and explain what this box plot tells you about the distribution of the data.
- Show outliers on the box plot, with an explanation of how outliers are determined. Give the quartiles and IQR in this explanation.
- Include the histogram of the data and a description of the shape of the distribution.
- Give a summary of your findings in Part 2 of this project:Include the three confidence intervals with their correct interpretations.
- Include all the steps of hypothesis test with correct interpretation.
- Include a discussion of comparison of the results of hypothesis test and of the confidence interval for the difference of two means.
- Put your data (both male and female sets) in Appendix A. Remember to document your sources.
- At the end of the paper in Appendix B include an explanation of what you have learned (about statistics) by completing this project.
- NOTE:Your report should follow APA guidelines.
- Any tables and graphs from Excel should be cut and pasted into the text of the Word document.
- Make sure your report has a cp.
- Make sure to title your paper with a running header labeled with your name, the class number, and the assignment title.
- Make sure your report has introduction, body, and conclusion parts.
