Question 185516
Suppose that the scores on the test are normally distributed with a mean of 570 and a standard deviation of 120. The individuals who exceed 800 on this test are considered to be potential leaders. What proportion of the population are considered to be potential leaders? Round your answer to at least four decimal places.
--------------------
z(800) = (800-570)/120 = 1.91667
---------
P(z > 1.91667) = 0.02764...
