Multiple Choice

Instruction 10-9
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 Instruction 10-9,if the firm wanted to test whether a greater proportion of workers would currently like to attend a self-improvement course than in the past,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
