The first pic is the question. Since some tutors have been solving the problems wrong recently (no judgment), I’ve added a sample question to solve problem. Recreational Time A researcher wishes to see if there is a difference between the mean number of hours per week thata family with no children participates in recreational activities and a family with children participates in recreationalactivities. She selects two random samples and the data are shown. Use u, for the mean number of families with nochildren. At a = 0.05, is there a difference between the means? Use the critical value method and tables.No children8.82.535Children10.12.935Send data to ExcelPart: 0 / 5Part 1 of 5(a) State the hypotheses and identify the claim.Ho:(Choose one) ▼H:|(Choose one) ▼This hypothesis test is a (Choose one) v test.

This is equivalent to H: H, =H.The alternative hypothesis is the statement that there is a difference between the means. This is equivalent to H,: H, #µy.The problem asks, "Are the mean number of hours per week that a family with no children participates in recreational activities and a family with children participates inrecreational activities different?" Hence, the claim is the alternative hypothesis.(b) Find the critical values.From the figure, for a two-tailed test with a= 0.01, the critical values are z=12.58.a= 0.10, C.V.=±1.65¥ = ri : °Ha= 0.05, C.V.-±1.96H :H#ka- 0.01, C.V.-£2.58(c) Compute the test value.Using the formula for the z test for comparing two means from independent populations, compute the test value:(X,- X2)- (H, – H2)(8.9 – 10.8) – 02.62 2.823434=-2.90Hence, the test value rounded to 2 decimal places is z= - 2.90.(d) Make the decision.Since the test value does fall in the critical region, reject the null hypothesis.-2.90 -2.582.58(e) Summarize the results.
