Tompkins Associates reports that the mean clear height for a
Class A warehouse in the United States is 22 feet. Suppose clear
heights are normally distributed and that the standard deviation is
4 feet. A Class A warehouse in the United States is randomly
selected.
(a) What is the probability that the clear height
is greater than 17 feet?
(b) What is the probability that the clear height
is less than 13 feet?
(c) What is the probability that the clear height
is between 25 and 31 feet?
(Round the values of z to 2 decimal places. Round your
answers to 4 decimal places.)
