Assume that military aircraft use ejection seats designed for men weighing between 132.9 lb and 215 lb. If​ women's weights are normally distributed with a mean of 171.5 lb and a standard deviation of ​48.4 lb, what percentage of women have weights that are within those​ limits? Are many women excluded with those​ specifications?

Suppose the mean number of candies in a standard vending machine bag is 47.6 with a standard deviation of 1.3 . assume that the number of candies is normally distributed what percentage of bags have less than 45 candies?

An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between  140lb and  181lb. The new population of pilots has normally distributed weights with a mean of 150 lb and a standard deviation of 34.8 lb.

the height of American men is normally distributed with a mean of 70 in and a standard deviation of 3 in. what are the heights in inches that define the most extreme 8% of the population of American men?

Assume that military aircraft use ejection seats designed for men weighing between 142.6 lb and 209 lb. If​ women's weights are normally distributed with a mean of 163.4 lb and a standard deviation of 42.8 ​lb, what percentage of women have weights that are within those​ limits? Are many women excluded with those​ specifications? The percentage of women that have weights between those limits is

Humerus bones from the same species of animal have approximately the same length-to-width ratios. It is known that Species A has a mean ratio of 5.9. Suppose that 100 fossil humerus bones were unearthed at a site where Species A is known to have flourished. (We assume that all bones are from the same species.) The length-to-width ratios of these bones have a sample mean 5.6 and sample standard deviation 0.25.   Can we conclude that the mean ratio of these bones is significantly smaller than those of Species A? Test with a 0.01 significance level.   What is the standard error?

A survey found that women's heights are normally distributed with mean 63.8 in and standard deviation 2.4 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? Click to view page 1 of the table. Click to view page 2 of the table. 1%. a. The percentage of women who meet the height requirement is (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? OA. Yes, because a large percentage of women are not allowed to join this branch of the military because of their height. OB. No, because the…

1) A​ half-century ago, the mean height of women in a particular country in their 20s was 63.7 inches. Assume that the heights of today's women in their 20s are approximately normally distributed with a standard deviation of 2.31 inches. If the mean height today is the same as that of a​ half-century ago, what percentage of all samples of 26 of today's women in their 20s have mean heights of at least 65.04 ​inches?

Assume that military aircraft use ejection seats designed for men weighing between 137.2 lb and 206 lb. If​ women's weights are normally distributed with a mean of 167.5 lb and a standard deviation of 41.1 lb, what percentage of women have weights that are within those​ limits? Are many women excluded with those​ specifications?
