Refer to Data Set 1 in Appendix B and test the claim that the mean body mass index (BMI) of men is equal to the mean BMI of women. Use Excel and/or SAS to perform the hypothesis test. Assume that the two samples are independent simple random samples selected from normally distributed populations. Do not assume that the population standard deviations are equal. Use "Example Hypothesis Test of Treatment for Bipolar Depression" on page 391 of the textbook as a guide for your test
