The goal of the study is to determine if the population mean SSATL score for the Japanese is different from the Americans' mean SSATL score. Assuming 10% level of significance (α)and a pooled variance test, please answer the following questions.
1. State your null and alternate hypotheses:
2. What is the value of the test statistic? Please show all the relevant calculations.
3. What is the rejection criterion based on critical value approach?
4. What is the Statistical decision (i.e. reject /or do not reject the null hypothesis)? Please also show the justification for your decision.

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. Using the above information, suppose that the test statistic is 2.45. Find the p-value if we assume that the alternative hypothesis was a two-tailed test ( H1 : μA - μJ ≠ 0 ). 0.0142 0.0071 0.4929 0.9858

An industrial psychologist is investigating the effects of work environment on employee attitudes. A group of 20 recently hired sales trainees were randomly assigned to one of four different “home rooms” – five trainees per room. Each room is identical except for wall color. The four colors used were green, blue, gray and red. The psychologist wants to know whether room color has an effect on attitude, and, if so, wants to compare the mean attitudes of the trainees assigned...
