A HR manager in a Global Corporation is interested in finding out whether newly hired Japanese managers are higher paid than their American counterparts. She randomly sampled 30 recently hired managers and recorded data concerning their salaries. The result of the pooled-variance t test of the mean salaries of the Japanese managers (Population 1) and the American managers (Population 2) in the sample is presented below Referring to the table above, and taking into account the specified data given in each sub-question answer the question below: The HR manager was attempting to show statistically that the recently hired Japanese managers have a significantly lower mean salary than the recently hired American managers . The proper conclusion for this test is: A. at the α = 0.10 level, there is sufficient evidence to indicate that the recently hired Japanese managers have a higher mean salary than their American counterparts. B. at the α = 0.10 level, there is sufficient evidence to indicate a difference in the mean salaries of recently hired Japanese and American managers. C. at the α = 0.10 level, there is insufficient evidence to indicate any difference in the mean salaries of recently hired Japanese and American managers. D. at the α = 0.10 level, there is sufficient evidence to indicate that the recently hired Japanese managers have a lower mean salary than their American counterparts.
