A recent study posed the question about whether Japanese managers are more motivated than American managers.A randomly selected sample of each was administered the Sarnoff Survey of Attitudes Toward Life (SSATL),which measures motivation for upward mobility.The SSATL scores are summarized below. Which of the following is the correct the null and alternative hypotheses to determine if the average SSATL score of Japanese managers differs from the average SSATL score of American managers? A)H₀ : μ_A - μ_J ≥ 0 versus H₁ : μ_A - μ_J 0 C)H₀ : μ_A - μ_J = 0 versus H₁ : μ_A - μ_J ≠ 0 D)H₀ : _A -_J = 0 versus H₁ :_A -

Quizplus · Accepted Answer

The correct null and alternative hypotheses to determine if the average SSATL score of Japanese managers differs from the average SSATL score of American managers are H₀ : μ_A - μ_J = 0 (no difference) versus H₁ : μ_A - μ_J ≠ 0 (difference). This matches choice C. Options A and B have the wrong inequality signs and D is written in an unclear format.
