Recreational Time A researcher wishes to see if there is a difference between the mean number of hours per week that a family with no children participates in recreational activities and a family with children participates in recreational activities. She selects two random samples and the data are shown. Use $\mu_1$ for the mean number of families with no children. At $\alpha = 0.10$, is there a difference between the means? Use the critical value method and tables. $\bar{X}$ $\sigma$ $n$ No children 8.9 2.9 20 Children 10.1 2.9 20
