Q: Successful hotel managers must have personality characteristics often thought of as feminine as well as those often thought of as masculine.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 y(bar) = 5.29. The mean score for the general male population is mean = 5.19. Do hotel managers on the average differ significantly in femininity score from men in general? Assume that the standard deviation of scores in the population of all male hotel managers is the same as the standard deviation = 0.78 for the adult male population.
(a) State null and alternative hypothesis in terms of the mean femininity score mean for male hotel managers.
(b) Find the z test statistic
(c) What is the P-value for your z ? What do you conclude about male hotel managers?
