Researchers asked to groups of students how many sex partners they have had in the previous year. one group was composed of 250 physical education majors who regularly participated in sports; the other group was compsed of 50 biology majors who did not regularly do sports. the distribution of number of sex partners is shown below. biology majors claimed an average of 1.24 sex partners in the previous year, while sports majors claimed an average of 2.4 partners in the prevous year. As you can see, the distributions are very differnt from a normal distribution, and even with log transformation the distributions are not normal. as a result, the researches used a mann-whitney u-test to compare the median numbers of sex partners for the two groups. The found U1 value corresponding to the biology majors was 8500.5 while the U2 value corresponding the the sports majors was 3999.5.1. Finish the mann-whitney u-test for them. state the hypothesis and reach a conclusion.2. comment on your results in light of the assumptions of the mann-whitney u-test.3. the researchers would like to know the actual number of sex partners for indivuals in the two groups, rather than just the claimed number. what improvments do can you suggest to their study design to acheive this goal?
