Transcribed Image Text: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 64.8 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=0.10 level of significance.
