Confidence Interval

Refer to Data Set 1a & 1b attached and use the sample data with Excel and/or SPSS to accomplish the following:

1. Construct a 99% confidence interval estimate of the mean body mass index for men.

2. Construct a 99% confidence interval estimate of the mean body mass index for women.

3. Compare and interpret the results. It is known that men have a mean weight that is greater than the mean weight for women, and the mean height of men is greater than the mean height of women. Do men also have a mean body mass index that is greater than the mean body mass index of women?
