Are the motivation scores of Japanese managers different from those of 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.

Japanese

American

Sample Size

10 (n1)

10 (n2)

Sample Mean SSATL Score

65(X1bar)

85(X2bar)

Sample Std. Dev.

20(s1)

20(s2)

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 5% 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 are the rejection criteria 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.

A screening procedure was designed to measure attitudes towards minorities as managers. High scores indicate negative attitudes and low scores indicate positive attitudes. Independent random samples were taken of 151 male financial analysts and 108 female analysts. For the former group, the sample mean and standard deviation scores were 85.8 and 19.13, whereas the corresponding statistics for the latter group were 71.5 and 12.2. Test the null hypothesis that the two population means are equal against the alternative that the...

The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitude toward school, and study habits of students. Scores range from 0 to 200, with 200 being the highest level of motivation. The mean score for U.S. college students is about 115, and the standard deviation is about 30. A teacher who suspects that older students have better attitudes toward school gives the SSHA to 20 students who are at least 30 years of...

(17.32) Successful hotel managers must have personality characteristics often thought of as feminine (such as “compassionate”) as well as those often thought of as masculine (such as “forceful”). The Bem Sex-Role Inventory (BSRI) is a personality test that gives separate ratings for female and male stereotypes, both on a scale of 1 to 7. A sample of 148 male general managers of three-star and four-star hotels had mean BSRI femininity score x¯¯¯x¯ = 5.29. The mean score for the general...

A sample is selected from a population with mean score of µ = 50. After a treatment is administered to the individuals in the sample, the mean is found to be M = 55 and the variance is s2 = 64. A. Assume that the sample has n = 4 scores. Conduct a hypothesis test to evaluate the significance of the treatment effect and calculate Cohen’s d to measure the size of the treatment effect. Use a two-tailed test with...
