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 63 9 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 03 Explain what this value represents c Write a conclusion for this hypothesis test assuming an x 0 10 level of significance CALLY mean marginis 03 7 RIGHTS B There is a 0 03 probability of obtaining a sample mean height of 63 7 inches or taller from a population whose mean height is 63 9 inches OC There is a 0 03 probability of obtaining a sample mean height of exactly 63 9 inches from a population whose mean height is 63 7 inches D There is a 0 03 probability of obtaining a sample mean height of 63 9 inches or shorter from a population whose mean height is 63 7 inches c Write a conclusion for this hypothesis test assuming an x 0 10 level of significance O A Reject the null hypothesis There is not sufficient evidence to conclude that the mean height of women 20 years of age or older is greater today OB 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 O C Do not 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 OD Do not reject the null hypothesis There is not sufficient evidence to conclude that the mean height of women 20 years of age or older is greater today
