###### Question:

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 testis 0.02. Explain what this value represents (c) Write a conclusion for this hypothesis foot assuming an a 0.05 level of significa (a) State the appropriate null and alternative hypotheses to assess whether women are for today OA H OC. H: OEH -64.5 in. versus H>64.5 in 63.7 in. versus H, 63.7 in 645 in versus H 64.5 in. OB 64.5 in versus H 64.5 in. OD. Hop=65.7 in versus Hy<63.7 in. OR H 63.7 in versus H 63.7 in. (b) Suppose the value for this testis 0.02. Explain what this value represents OA. There is a 0.02 probability of obtaining a sample mean height of 64.5 inches or shorter from a population whose mean higis 69.7 inches OB. There is a 0.02 probability of obtaining a sample mean height of 63.7 inches or taler from a population whose mean height is 645 inches OG There is a 0.02 probability of b ring a sample mean height of exactly 64.5 inches from a population whose man height is 03.7 inch OD . There is a 0.02 probability of obtaining a sample mean height of 64.5 inches or taller from a population whose mean i s 63.7 inches (c) Write a conclusion for this typothesis test assuming an 0.05 level of significance O A. Do not reject the nul hypothesis. There is sufficient evidence to conclude that the mean height of women 20 years of age or older is greater today OB. Do not reject the nullhypothesis. There is not sufficient evidence to conclude that the mean height of women 20 years of age or older is greater today O C Reject the null hypothesis. There is not suicient evidence to conclude that the mean height of women 20 years of age or older is greater today OD. Reject the null hypothesis. There is sufficient evidence to conclude that the mean height of women 20 years of age or older is greater today Click to select your answer.
