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.MeanMedianModeMidrangeRangeVarianceStandard DeviationDiscuss 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?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_mod05_homework.docxg310_scenario_option1.docx

Week 4 Project - STAT 3001 Student Name: <Type your name here> Date:<Enter the date on which you began working on this assignment.> Instructions:To complete this project, you will need the following materials: STAT DISK User Manual (found in the classroom in Doc Sharing)Access to the internet to download the Stat Disk program. Part I.Analyze Data Instructions Answers Open the file Passive and Active Smoke using menu option Datasets and then Elementary Stats, 13th Edition.This file contains some information on the continine levels in smokers, nonsmokers exposed to smoke (ETS), and nonsmokers not exposed to smoke (No ETS). How many observations are there in this file?What would you expect to find relative to the continine level in the groups? Part II. Descriptive Statistics 3-6 Generate descriptive statistics for No ETS, Smokers and ETS groups and complete the following table.Round mean and standard deviation to 3 decimal places. Variable Sample Mean Sample Standard Deviation Sample Size No ETS Smokers ETS 7. Did you get the results you expected here?Explain why. 8. Which of the three groups experienced the MOST variation? How do you know? Part III. Confidence Intervals 9. Generate a 90% interval for the mean of the No ETS group. Paste your results here. 10. Generate a 90% interval for the mean of the Smoker group. Paste your results here. 11. Generate a 90% interval for the mean of the ETS group. Paste your results here 12. Create a graph below by illustrating all three confidence intervals on one graph using the tools in your word processor (example below).Stat Disk cannot do this for you. Create your graph and turn the font red.For this process, I just used the dashes and wrote a scale below the axes. Here is an example, but it is not based on the data you are analyzing: Case 114---------------------42 Case 235-------------------------70 ________________________________________ 0204060 Your Solution: 13. Based on the confidence intervals shown above, what conclusion can you draw about whether the exposure to smoke leads to higher continine levels? Why? Part IV. Hypothesis Testing 14. Your researcher’s claim is that the continine level for the ETS group is not equal to zero. Compose a hypothesis test with a level of significance of .05 to test your claim. Step 1.Determine parameter of interest and compose null and alternative hypotheses. Step 2.Determine the sample mean, sample standard deviation, and sample size.[Hint:You recorded these previously in Part II, #3-6] Step 3.Determine the likelihood that the population mean is actually not equal to 0 by completing a Hypothesis Test: One Mean in STAT DISK.Use significance of 0.05.Remember to change the pulldown option in Stat Disk to agree with the alternate hypothesis. Paste your results here. Step 4.State your conclusion.Your conclusion statement should include the p-value and level of significance to phrase your conclusion. 15. For your second hypothesis test, your researcher’s claim is that the continine level in the NO ETS group is greater than zero.Perform a hypothesis test using a significance level of .01 to test your claim. Step 1.Determine parameter of interest and compose null and alternative hypotheses. Step 2.Determine the sample mean, sample standard deviation, and sample size.[Hint:You recorded these previously in Part II, #3-6] Step 3.Determine the likelihood that the population mean is actually greater than 0 by completing a Hypothesis Test: One Mean in STAT DISK.Use significance of 0.01.Remember to change the pulldown option in Stat Disk to agree with the alternate hypothesis. Paste results here. Step 4.State your conclusion. Your conclusion statement should include the p-value and level of significance to phrase your conclusion. 16. Answer the following questions based on the above hypothesis test. a.What is the p-value for the hypothesis test in #15 and what does it represent? (Look at page 383 in the text) b.Given that your data, hypotheses, and p-value do not change, what would need to be different in order for you to REJECT the null hypothesis? (What do you compare to make your rejection decision?) Submit your final draft of your Word file by going to Week 4, Project, and follow the directions under Week 4 Assignment 2.Please use the naming convention "WK4Assgn2+first initial+last name" as the Submission Title.
