Question 665410: Assume that the population of heights of male college students is approximately normally distributed with mean m of 73.16 inches and standard deviation s of 6.39 inches. A random sample of 70 heights is obtained. Show all work.
(A) Find P(x>74.50
(B) Find the mean and standard error of the x-bar distribution
(C) Find P(x-bar>74.50
(D) Why is the formula required to solve (A) different than (C)?
You can put this solution on YOUR website! µ=73.16 inches+σ=6.39
random sample=70height
m=73.16 inches and s=6.39/√70
p(bar over x =74.50)
=p(z=74.50-73.16/6.39√70
