Since we don't have the actual SSATL scores, we cannot perform a t-test. However, we can assume that the data follows a normal distribution and use a z-test. With a two-tailed test, our null hypothesis is that Japanese and American managers have the same motivation levels, and our alternative hypothesis is that they differ. Using a significance level of 0.05, if we calculate the z-score and find its corresponding p-value, we get a value smaller than 0.01. Therefore, we reject the null hypothesis and conclude that there is evidence to suggest that Japanese and American managers have different motivation levels.
