A recent study focused on the number of times men and women who live alone buy take-out dinner in a month. Assume that the distributions follow the normal probability distribution and the population standard deviations are equal. The information is summarized below.
Statistic: Men Women
The sample mean: 24.51 22.69
Sample standard deviation: 4.48 3.86
Sample size: 35 40
At the 0.01 significance level, is there a difference in the mean number of times men and women order take-out dinners in a month?
a. State the decision rule for 0.01 significance level: H0: μMen= μWomen H1: μMen ≠ μWomen. (Negative amounts should be indicated by a minus sign. Round your answers to 3 decimal places.)
Reject H0 if t < or t >
b. Compute the value of the test statistic. (Round your answer to 3 decimal places.)
c. What is your decision regarding the null hypothesis?
d. What is the p-value?
