Find the P-value for the indicated hypothesis test.
A random sample of 139 forty-year-old men contains 26% smokers. Find the P-value for a test of the claim that the percentage of forty-year-old men that smoke is 22%.
First identify the following Population mean: 22% Sample size = 139 Sample mean: 26% Z = (sample mean - population mean)/sqrt((pop mean*(1-pop mean))/sample size
Z = 0.04/sqrt((0.22)(0.78))/139 Z= 1.1384 P value using z score table is 0.8729 But that is for values within that range we want values greater than 22%. So it would be 1-0.8729 = 0.1271 or A
