Height of men is normally distributed with a mean of 69 in, and a standard deviation of 2.8 in. and half of 200 passengers are men. Find z score of the sample means. Find the probability that mean height of 100 men is less than 72 in.

Answer 1

Explanation:

a) 0.6406; b) 1.000; c) C. The probability from part​ (a) is more relevant because it shows the proportion of male passengers that will not need to bend; d) B. Since men are generally taller than​ women, a design that accommodates a suitable proportion of men will necessarily accommodate a greater proportion of women.
