A corporation randomly selects 150 salespeople and finds that 66% who have never taken a self-improvement course would like such a course. The firm did a similar study 10 years ago in which 60% of a random sample of 160 salespeople wanted a self-improvement course. The groups are assumed to be independent random samples. Let π1 and π2 represent the true proportion of workers who would like to attend a self-improvement course in the recent study and the past study, respectively. If the firm wanted to test whether a greater proportion of workers would currently like to attend a self-improvement course than in the past, which represents the relevant hypotheses? A. H0:π1−π2≠0 versus H1:π1−π2=0 B. H0:π1−π2≥0 versus H1:π1−π2<0 C. H0:π1−π2≤0 versus H1:π1−π2>0 D. H0:π1−π2=0 versus H1:π1−π2≠0

A corporation randomly selects 150 salespeople and finds that 66% who have never taken a self-improvement course would like such a course. The firm did a similar study 10 years ago in which 60% of a random sample of 160 salespeople wanted a self-improvement course. The groups are assumed to be independent random samples. Let π1 and π2 represent the true proportion of workers who would like to attend a self-improvement course in the recent study and the past study, respectively. If the firm wanted to test whether a greater proportion of workers would currently like to attend a self-improvement course than in the past, which represents the relevant hypotheses?
A.
H0:π1−π2≠0 versus H1:π1−π2=0
H0:π1−π2≥0 versus H1:π1−π2<0
H0:π1−π2≤0 versus H1:π1−π2>0
H0:π1−π2=0 versus H1:π1−π2≠0
