Question

A researcher tests whether Japanese managers are more motivated than American managers using the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation for upward mobility. A randomly selected group of each were administered The SSATL scores are summarized below.

	Sample mean SSATL score	Sample Standard deviation	Sample size
American	78.5	11.1	210
Japanese	79.5	6.4	100

Suppose α = 0.01. Which of the following represents the correct conclusion?

Answer 1

We use Minitab to solve this question-

P-value = 0.159 > alpha = 0.01 , Therefore Japanese managers are not more motivated than American managers.

Conclusion- From given sample information, there is not enough / insufficient evidence to say that Japanese managers are more motivated than American managers.
