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 H₁ for the mean number of families with no children. At a=0.10, is there a difference between the means? Use the critical value method and tables. No children Children Send data to Excel X 847 10.6 6 2.6 2.9 n 32 32
