Instruction 10-1
Are Chinese managers more motivated than Australian 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 summarised below.
$\begin{array} { | l | l | l | } \hline & \text { Australian } & \text { Chinese } \\\hline \text { Sample Size } & 211 & 100 \\\hline \text { Mean SSATL Score } & 65.75 & 79.83 \\\hline \text { Population Std. Dev. } & 11.07 & 6.41 \\\hline\end{array}$
-Referring to Instruction 10-1,suppose that the test statistic is Z = 2.45.Find the p-value if we assume that the alternative hypothesis was a two-tailed test (H₁: ?_A - ?_J ? 0) .

Since it's a two-tailed test, we need to find the area in both tails. A Z-score of 2.45 has an area of 0.0142 in the right tail. Therefore, the p-value is 2 x 0.0142 = 0.0284. However, since the alternative hypothesis is not specifying the direction of the difference, we need to consider both tails, so the final p-value is 0.0284 x 2 = 0.0568, which is smaller than 0.1. Therefore, we reject the null hypothesis and conclude that there is evidence of a difference in motivation for upward mobility between Chinese and Australian managers.
