Question 1075123: The mean height of women in a country (ages 20−29) is 64.1 inches. A random sample of 65 women in this age group is selected. What is the probability that the mean height for the sample is greater than 65 inches? Assume σ=2.67 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z)=(x-mean)/sigma/sqrt (n)
=(65-64.1)/2.67/sqrt (65)
=0.9*sqrt(65)/2.67=2.72
It is probability z>2.72, and that is 0.0033.
