Week 4 Project – STAT 3001Student Name: Date: 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 InstructionsAnswers 1. 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?There are forty (40) observations in this file. 2. 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.VariableSample MeanSampleStandard DeviationSample 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 here12. 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 1 14———————42Case 2 35————————-70 ________________________________________ 0 20 40 60 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 Testing14. 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?)
