Do Men Talk Less Than Women?

The accompanying table gives results from a study of the words spoken in a day by men and women, and the original data are in Data Set 17 in Appendix B (based on “Are Women Really More Talkative Than Men?” by Mehl et al., Science, Vol. 317, No. 5834). Use a 0.10 significance level to test the claim that the mean number of words spoken in a day by men is less than that for women.

Men                 n1= 100   mean = 15668.5   s= 8632.5

Women           n2 = 210 mean = 16215       s=7301.2
