question 49

Multiple Choice

TABLE 10-11
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 10-11, if the firm wanted to test whether this proportion has changed from the previous study, which represents the relevant hypotheses?

• A) H₀ : π₁ - π₂ = 0 versus H₁: π₁ - π₂ ≠ 0
• B) H₀ : π₁ - π₂ ≠ 0 versus H₁ : π₁ - π₂ = 0
• C) H₀ : π₁ - π₂ ≤ 0 versus H₁ : π₁ - π₂ > 0
• D) H₀ : π₁ - π₂ ≥ 0 versus H₁ : π₁ - π₂ < 0
