Successful hotel managers must have personality characteristics often traditionally stereotyped as feminine (such as "compassionate") as well as those traditionally stereotyped as masculine (such as "forceful"). The Bem SexRole Inventory (BSRI) is a personality test that gives separate ratings for "female" and "male" stereotypes, both on a scale of 11 to 77. Although the BSRI was developed at a time when these stereotypes were more pronounced, it is still widely used to assess personality types. Unfortunately, the ratings are often referred to as femininity and masculinity scores.

A sample of 148148 male general managers of threestar and fourstar hotels had mean BSRI femininity score =5.29=5.29. The mean score for the general male population is =5.19=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 =0.78=0.78 for the adult male population.
