Week 4 Project – STAT 3001Student Name:Kelishia Williams-NelsonDate: 6/19/2017Instructions: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 DataInstructionsAnswers1.Open the filePassive andActive Smokeusing menuoptionDatasetsand thenElementary Stats, 13thEdition.This file containssome information on thecontinine levels in smokers,nonsmokers exposed tosmoke (ETS), andnonsmokers not exposed tosmoke (No ETS).How manyobservations are there in thisfile?The file Passive and Active smoke has 40 observations for the 3variables listed.2.What would you expect tofind relative to the contininelevel in the groups?I would expect the levels on continine to be increased in those whoactively smoke, decreased in people who are exposed to secondhand smoke and none in people who do not smoke and are notexposed to second hand smoke.Part II. Descriptive Statistics3-6 Generate descriptivestatistics for No ETS,Smokers and ETS groups andcomplete the following table.Round mean and standarddeviation to 3 decimal places.VariableSampleMeanSampleStandardDeviationSample SizeNo ETS60.575138.08340Smokers172.475119.49840ETS16.3562.533407. Did you get the results youexpected here?Explain why.Yes, the results are basically what I expected.Smokers hadthe highest levels of continine due to the increased intake.Smokers exposed to smoke had a decreased amount ofcontinine and nonsmokers had the lowest amount ofcontinine due to the least exposure to smoke.8. Which of the three groups1

experienced the MOSTvariation? How do youknow?Part III. Confidence Intervals9. Generate a 90% intervalfor the mean of the No ETSgroup. Paste your resultshere.10. Generate a 90% intervalfor the mean of the Smokergroup. Paste your resultshere.11. Generate a 90% intervalfor the mean of the ETSgroup. Paste your results here12. Create a graph below by illustrating all three confidence intervals on one graph using the tools inyour word processor (example below).Stat Disk cannot do this for you. Create your graph and turnthe 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———————42Case 235————————-70________________________________________0204060Your Solution:13. Based on the confidenceintervals shown above, whatconclusion can you drawabout whether the exposure tosmoke leads to highercontinine levels? Why?2
