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 μ1 for the mean number of families with no children. At =α0.05, is there a difference between the means? Use the critical value method and tables. State the hypotheses and identify the claim. H0: Claim or not a Claim H1: Claim or not a claim Find the Critical Value(s): Round answer to at least 3 decimal places. Compute the test Value: Round the answer to at least 3 decimal places. Make the decision Summarize the results. There is or is not enough evidence to support the claim or reject the claim.
