White blood cell counts are helpful for assessing liver disease, radiation, bone marrow failure, and infectious diseases. Listed below are white blood cell counts found in a simple random sample of men and women (based on data from the Third National Health and Nutrition Examination Survey).  Set up your data file so Female = 2; Male = 1. Using a .01 significance level, test the claim that men and women have different white blood cell counts. Based on the 95% confidence interval, what conclusions can be drawn about the mean difference between men and women?   Female:           8.9       6.5       9.45     9.65     6.4       5.15     16.6     5.75     11.6     5.90                             9.30     8.55     10.8     4.85     4.90            8.75     6.90     9.75     4.05     9.05                             5.05     6.4       4.05     7.60     4.95     3.00     9.10   Male                5.25     5.95     10.05   5.45     5.30     5.55     6.85     6.65     6.3       6.40                             7.85     7.70     5.30     6.50     4.55     7.10            8.00     4.70     4.40     4.90
