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. If convenient, use technology to find the probability. For a sample of n = 32, find the probability of a sample mean being less than 12,748 or greater than 12,751 when μ = 12,748 and a = 1.5. For the given sample, the probability of a sample mean being less than 12,748 or greater than 12,751 is. (Round to four decimal places as needed.)

Question
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. If convenient, use technology to find the
probability.
For a sample of n = 32, find the probability of a sample mean being less than 12,748 or greater than 12,751 when
u=12,748 and a = 1.5.
For the given sample, the probability of a sample mean being less than 12,748 or greater than 12,751 is.
(Round to four decimal places as needed.)
