(Solution Document) A corporation randomly selects 150 salespeople and finds that 100 who have never taken a self-improvement course would like such a course.


A corporation randomly selects 150 salespeople and finds that 100 who have never taken a self-improvement course would like such a course. The firm did a similar study 10 years ago in which 96 out of a random sample of 160 salespeople wanted a self-improvement course. The groups are assumed to be independent random samples. Let p1 and p2 represent the true proportion of workers who would like to attend a self-improvement course in the recent study and the past study, respectively.

What is the value of the test statistic to use in evaluating the alternative hypothesis that there is a difference in the two population proportions? Round your answer to 3 decimal places.
