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 64.5 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 0.01. 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, u= 63.7 in. versus H,: u# 63.7 in. O B. Ho: u= 63.7 in. versus H,: u> 63.7 in. OC. Ho u= 64.5 in. versus H,: u < 64.5 in. O D. Ho: u= 63.7 in. versus H,: u< 63.7 in. O E. H u= 64.5 in. versus H,: u> 64.5 in. OF. Ha H= 64.5 in. versus H,: u# 64.5 in. (b) Suppose the P-value for this test is 0.01. Explain what this value represents. O A. There is a 0.01 probability of obtaining a sample mean height of exactly 64.5 inches from a population whose mean height is 63.7 inches. O B. There is a 0.01 probability of obtaining a sample mean height of 64.5 inches or shorter from a population whose mean height is 63.7 inches. OC. There is a 0.01 probability of obtaining a sample mean height of 64.5 inches or taller from a population whose mean height is 63.7 inches. O D. There is a 0.01 probability of obtaining a sample mean height of 63.7 inches or taller from a population whose mean height is 64.5 inches. (c) Write a conclusion for this hypothesis test assuming an a = 0.10 level of significance.
