Acorporation 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 1 and 2 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?
