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 64.4 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 0.19. Explain what this value represents. (c) Write a conclusion for this hypothesis test assuming an a = 0.10 level of significance. (a) State the appropriate null and alternative hypotheses to assess whether women are taller today. O A. H,: µ= 64.4 in. versus H,: p# 64.4 in. O B. H: u= 64.4 in. versus H,: p < 64.4 in. OC. Ho: µ= 63.7 in. versus H,: µ# 63.7 in. O D. H,: µ= 64.4 in. versus H,: µ > 64.4 in. O E.
