Use the traditional method to test the given hypothesis. Assume that the pop Heights of men aged 25 to 34 have a standard deviation of 2.9. Use a 0.05 significance level totest the claim that the heights of women aged 25 to 34 have a different standard deviation. Theheights (in inches) of 16 randomly selected women aged 25 to 34 are listed below. Round thesample standard deviation to five decimal places.52.13 65.09 64.18 66.72 63.09 61.15 67.50 64.6553.80 64.21 60.17 68.28 66.49 62.10 65.73 64.72Select the correct conclusion based on the null hypothesis and final conclusion.O Reject Ho. There is not sufficient evidence to support the claim that heights of women aged 25 to 34have a standard deviation greater than 2.9 in.O Fail to reject Ho. There is not sufficient evidence to support the claim that heights of women aged 25 to34 have a standard deviation different from 2.9 in.O Fail to reject Ho. There is sufficient evidence to support the claim that heights of women aged 25 to 34have a standard deviation less than 2.9 in.O Reject Ho.

Phil wanted to know if mothers give more hugs to their children than fathers do. He used 8 married couples so that each mother and father would be matched on the number of children for his sample. Dr. Phil then asked each parent to report the number of hugs that they gave their children over the course of 2 weeks. Assume the parametric assumptions were NOT violated. Conduct an appropriate statistical test for him using alpha .05 and the eight steps of hypothesis testing.

A blind taste test is conducted to determine which of two colas, Brand A or Brand B, individuals prefer.

For which values of p0 do you not reject the null hypothesis? What do each of the values of p0 represent? Do not reject the null hypothesis for the values of p0 between _ and _,inclusively.
Movie Theater Attendance: The data shown are the movie admissions, in thousands, of people attending movie theaters over two different time periods. At α = 0.05, is there a difference in the means for the movie attendance for these time periods? Use the traditional method of hypothesis testing unless otherwise specified. State the hypotheses and identify the claim. Find the critical value. Compute the test value. Make the decision. Summarize the results.
