Assume that military aircraft use ejection seats designed for men weighing between
The percentage of women that have weights between those limits is
The percentage of women that have weights between those limits is
Step 1 :We are given that women's weights are normally distributed with a mean of
Step 2 :We are asked to find the percentage of women whose weights fall within the range of
Step 3 :To solve this, we can standardize the weights using the z-score formula:
Step 4 :We calculate two z-scores: one for the lower limit (
Step 5 :The z-score for the lower limit is
Step 6 :We then find the probabilities corresponding to these z-scores using the standard normal distribution. The probability for the lower limit is
Step 7 :The difference between these probabilities gives us the percentage of women whose weights fall within the given range.
Step 8 :The percentage of women that have weights between those limits is
