Exercise 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 belowStatistic Men WomenSample mean 24.51 22.69Po?

H0: men mean - women mean = 0

Ha: men mean - women mean not equal to 0

Get the test statistic:

(24.51-22.69)/sqrt(4.48^2/35 + 3.86^2/40) = 1.871

The p value (from a table) is: About 0.06

This is well above the 0.01 significance, so we do not reject the null hypothesis. There is no statistic difference.
