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 %u03C01 and %u03C02 represent the true proportion of workers who would like to attend a self-improvement course in the recent study and the past study,

respectively.

Referring to the information above, 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?

1) 0

2) 1.96

3) 4.335

4) 1.50
