In 1990, the mean height of women 20 years of age or older was 63.7 inches based on data obtained from the cdc. suppose that a random sample of 45 women who are 20 years of age or older in 2015 results in a mean height of 63.9 inches with a standard deviation of 0.5 inch. does your sample provide sufficient evidence that women today are taller than in 1990? perform the appropriate test at the 0.05 level of significance
