How would you answer these questions completely based off R
code?
The heights of men in a certain population follow a normal
distribution with mean 69.7 inches and standard deviation 2.8
inches.
(a) If 10 men are selected at random, what is the prob- ability
their average height is above 72 inches?
(b) If exactly one man is selected at random, what is the
probability his height is above 72 inches?
(c) What is the 80th percentile for the average height of 10
men?
(d) How many men must be sampled to be 88% confident the true
height is within 2 inches?
