question 105

Multiple Choice

Instruction 15-1
A large organization randomly selects 150 employees and finds that 66% who have never taken a professional-development course would like such a course. The firm did a similar study 10 years ago in which 60% of a random sample of 160 employees wanted a professional-development 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 professional-development course in the recent study and the past study, respectively.
-Referring to Instruction 15-1,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
