The population mean and standard deviation are given below. Find the indicated probability and determine whether a sample mean in the given range below would be considered unusual. Ifconvenient, use technology to find the probability.

For a sample of n=40, find the probability of a sample mean being less than 12,751 or greater than 12,754 when =12,751 and =1.6.

For the givensample, the probability of a sample mean being less than 12,751 or greater than 12,754 is
