Several years ago, the mean height of women 20 years of age or older was 63.763.7 inches. Suppose that a random sample of 4545 women who are 20 years of age or older today results in a mean height of 64.164.1 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 0.130.13. Explain what this value represents. (c) Write a conclusion for this hypothesis test assuming an alphaαequals=0.100.10 level of significance.
