Question

27. A recent study focused on the number of times men and women who live alone buy
take-out dinner in a month. The information is summarized below.

Statistic&nb sp;                                                      Men                                   Women
Sample mean                                               24.51                                    22.69
Population standard deviation                      4.48                                       3.86
Sample size                                      & nbsp;              35                                          40

At the .01 significance level, is there a difference in the mean number of times men and
women order take-out dinners in a month? What is the p-value?

just the critical way not the p-value way.
