Studies conducted at the University of Melbourne indicate that there may be a difference between the pain thresholds ofblondes and brunettes. Men and women of various ages were divided into four categories according to hair color. Eachparticipant was given a pain threshold score based on his or her performance in a pain sensitivity test (higher scorehigher pain tolerance).Light BlondeDark BlondeLight BrunetteDark Brunette62634232605750397152415155413730484335a) State the null and alternative hypotheses.

Please see below. I am only given one opportunity at this. Please help!! 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 mangers of three-star and four-star hotels had mean BSRI femininity score of 5.29 with a SD of 0.78. The mean score for the general male population is μ=5.19. Do hotel managers on the average differ significantly in femininity score from men in general?
