Multiple Choice

TABLE 10-10
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.
-Referring to Table 10-10, what is/are the critical value(s) when testing whether population proportions are different if α = 0.10?

• A) ±1.645
• B) ±1.96
• C) -1.96
• D) ±2.08
