A random sample of 20 male BMI values is being compared to a random sample of 20 femaleBMI values:
Variable N N* Mean SE Mean StDev Minimum Q1 Median Q3
maleBMI 20 0 28.285 0.970 4.338 21.000 25.050 27.950 30.875
femaBMI 20 0 22.440 0.936 4.186 16.300 19.425 20.800 25.400
Variable MaximummaleBMI 37.300femaleBMI 32.300
(a) Test whether there is sufficient evidence to claim that the average male BMI exceeds theaverage female BMI by more than 3. Use the .05 level of significance. Assume that thepopulation variances are the same.
Note: I have the answer for this question, but I do not understand it. It is from an old test. Can someone please work me through the steps?
