SCENARIO 10-1
Are Japanese Managers More Motivated Than American Managers

SCENARIO 10-1
Are Japanese managers more motivated than American managers? A randomly selected group of each
were administered the Sarnoff Survey of Attitudes Toward Life (SSATL), which measures motivation
for upward mobility. The SSATL scores are summarized below. $$\begin{array} { l l l } & \text { American } & \text { Japanese } \\\text { Sample Size } & 211 & 100 \\\text { Sample Mean SSATL Score }& 65.75 & 79.83 \\\text { Sample Std. Dev. } & 11.07 & 6.41\end{array}$$
-Referring to Scenario 10-1, give the null and alternative hypotheses to determine if the mean SSATL score of Japanese managers differs from the mean SSATL score of American managers. a) $H _ { 0 } : \mu _ { A } - \mu _ { J } \geq 0$ versus $H _ { 1 } : \mu _ { A } - \mu _ { J } < 0$
b) $H _ { 0 } : \mu _ { A } - \mu _ { J } \leq 0$ versus $H _ { 1 } : \mu _ { A } - \mu _ { J } > 0$
c) $H _ { 0 } : \mu _ { A } - \mu _ { J } = 0$ versus $H _ { 1 } : \mu _ { A } - \mu _ { J } \neq 0$
d) $H _ { 0 } : \bar { X } _ { A } - \bar { X } _ { J } = 0$ versus $H _ { 1 } : \bar { X } _ { A } - \bar { X } _ { J } \neq 0$
