Q1) Successful hotel managers should have personality characteristics frequently thought of as feminine (like "compassionate") as well as those frequently thought of as masculine (such as "forceful"). Bem Sex-Role Inventory (BSRI) is personality test whihc gives separate ratings for female and male stereotypes, both on scale of 1 to 7. A sample of 148 male general managers of three-star and four-star hotels had mean BSRI femininity score = 5.29.Mean score for general male population is μ=5.19. Do hotel managers on average vary significantly in femininity score from men in general? Suppose that standard deviation of scores in population of all male hotel managers is same as the σ=0.78 for adult male population.
To give 98% confidence interval for population mean μ, you would use critical value.
Using a 5% level of significance, is there any difference in proportion of guests who would select the two resorts? What is your conclusion?
Additionally, student should use graphing function to graph data and calculate regression equation.
