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 64.9 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 0.16. Explain what this value represents. (c) Write a conclusion for this hypothesis test assuming an a = 0.05 level of significance. (a) State the appropriate null and alternative hypotheses to assess whether women are taller today. O A. Ho H = 63.7 in. versus H,: p 63.7 in. O E. Ho: H = 64.9 in. versus H,: [ > 64.9 in. OF. Ho: H = 63.7 in. versus Hy: u # 63.7 in
