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 probability. For a sample of n=38, find the probability of a sample mean being less than 12,750 orgreatrt than 12,753 when y= 12,750 and o= 1.2. For the given sample, the probability of a sample mean being less than 12,750 of greater than 12,753 is.
