Question

In one study of smokers who tried to quit smoking with nicotine patch therapy, 35 were smoking one year after treatment and 34 were not smoking one year after the treatment. Use a 0.05 significance level to test the claim that among smokers who try to quit with nicotine patch therapy, the majority are smoking one year after the treatment. Do these results suggest that the nicotine patch therapy is not effective? UB. Ho: p=0.5 Hy: p=0.5 Xe Ho-p=0.5 Hu: p <0.5 *. Ho: p=0.5 He: p > 0.5 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.)

Answer 1

solution: Given, na 35 + 34 69 x = 35 Ôn ê 1) 35 a 0.5072 69 Mull and alternative are Hoe pa 05 Hii p>0.5 Test statistic р-Ро = 23 POC1-20) 0.5072-0.5 Yoos (1-05) 69 Z - 0:12 pualue P[12call 20.12) 0-45224 - Chrom staástical table) 0.452 .
