Question 4 (1 point) 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 it1 and it2 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? O A) Ho: n1 - 12 * 0 versus H1 : 71 - 12 = 0 O B) Ho: nt1- 12 = 0 versus H1 : 1 - 12 # 0 O C) Ho: T1 - 12 5 0 versus H1 : It1 - 12 > 0 O D) Ho: 71 - 712 2 0 versus H1 : It1 - 12
