A branch of the military requires women's heights to be between 58 in and 80 in. 3. 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? Click to view page 1 of the table. Click to view page 2 of the table. a. The percentage of women who meet the height requirement is 98.61'%, (Round to two decimal places as needed.) 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 the percentage of women who meet the height requirement is fairly large. N B. No, because only a small percentage of women are not allowed to join this branch of the military because of their height. C. No, because the percentage of women who meet the height requirement is fairly small. D. Yes, because a large percentage of women are not allowed tojoin this branch of the military because of their height. h. For the new height requirements, this branch of the milimry requires women's heights to be at least 57.7V in and at most 68.6' in. (Round to one decimal place as needed.)

The survey also found that men's heights are normally distributed with mean 69.7 in. and standard deviation 3.9 in. Most of the live characters employed at an amusement park have height requirements of a mInImum of 56 in. and a maximum of 63 in Complete parts (a) and (b) belowt a. Find the percentage of men meeting the height requirement. What does the result suggest about the genders of the people who are employed as characters at the amusement park? The percentage of men who meet the height requirement is 4.27'%. (Round to two decimal places as needed.) Since most men do not mes? the height requirement, it is likely that most of the characters are women.' b. If the height requirements are changed to exclude only the tallest 50% of men and the shortest 5% of men, what are the new height requirements? The new height requirements are a minimum of 63.3' in. and a maximum of 69.1' in. (Round to one decimal place as needed.)
