Math Problem Statement

A survey found that​ women's heights are normally distributed with mean 63.8 in and standard deviation 2.3 in. A branch of the military requires​ women's heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too​ tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest​ 1% and the tallest​ 2%, what are the new height​ requirements?

Part 2 Are many women being denied the opportunity to join this branch of the military because they are too short or too​ tall? A. ​Yes, because a large percentage of women are not allowed to join this branch of the military because of their height. B. ​No, because the percentage of women who meet the height requirement is fairly small. C. ​Yes, because the percentage of women who meet the height requirement is fairly large. D. ​No, because only a small percentage of women are not allowed to join this branch of the military because of their height. Part 3 b. For the new height​ requirements, this branch of the military requires​ women's heights to be at least    enter your response here in and at most    enter your response here in. ​(Round to one decimal place as​ needed.)
