10 Homework K Question 17, 10.3.12 Part 1 of 3 HW Score: 57.5%, 11.5 of 20 points O Points: 0 of 1 Save Several years ago, the mean height of women 20 years of age or older was 63.7 inches. Suppose that a random sample of 45 women who are 20 years of age or older today results in a mean height of 63.9 inches. (a) State the appropriate null and alternative hypotheses to assess whether women are taller today. (b) Suppose the P-value for this test is 0.15. Explain what this value represents. (c) Write a conclusion for this hypothesis test assuming an α = 0.05 level of significance. (a) State the appropriate null and alternative hypotheses to assess whether women are taller today. OA.
