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 nequals=3232, find the probability of a sample mean being less than 12 comma 75112,751 or greater than 12 comma 75412,754 when muμequals=12 comma 75112,751 and sigmaσequals=1.91.9.
