Chapter 13, Problem 11BSC(choose chapter or problem)
use the Kruskal - Wallis test with the data set from Appendix B?. Nicotine in Cigarettes? Refer to Data Set in Appendix B and use the amounts of nicotine (mg per cigarette) in the king-size cigarettes, the 100-mm menthol cigarettes, and the 100-mm nonmenthol cigarettes. The king-size cigarettes are nonfiltered, nonmenthol, and nonlight. The 100-mm menthol cigarettes are filtered and nonlight. The 100-mm nonmen?thol cigarettes are filtered and nonlight. Use a 0.05 significance level to test the claim that the three categories of cigarettes yield the same median amount of nicotine. Given that only the king-size cigarettes are not filtered, do the filters appear to make a difference? Mile 1 3:15 3:24 3:23 3:22 3:21 Mile 2 3:19 3:22 3:21 3:17 3:19 Mile 3 3:34 3:31 3:29 3:31 3:29

ANSWER:Solution 11BSC Step 1 By using = 0.05 level of significance we nee o test the claim that the different size categories have the same median chest deceleration in the standard crash test The Hypotheses can be expressed as H0: the three categories of cigarettes yield the same median amount of nicotine. H : the three categories of cigarettes yield the different median amount of nicotine. 1 All these three samples are combined together to get a big sample. We first order the absolute values of the difference scores and assign rank from 1 through ‘n’ to the smallest through largest absolute values of the difference scores, and assign the mean rank when there are ties in the absolute values of the difference scores.
