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 7 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 0.17 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.
