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 0.17. 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.

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 64.4 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 0.17. 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. Ho: H = 63.7 in. versus H,: µ # 63.7 in.
O B. Ho: H = 64.4 in. versus H,: µ # 64.4 in.
O C. Ho: H = 63.7 in. versus H,: µ< 63.7 in.
D. Ho: H = 63.7 in. versus H,: µ > 63.7 in.
O E. Ho: µ = 64.4 in. versus H;: µ > 64.4 in.
O F. Ho: H = 64.4 in. versus H,: µ< 64.4 in.
