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= 38, find the probability of a sample mean being less than 12,748 or greater than 12,751 when u = 12,748 and o= 1.4. 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.) Would the given sample mean be considered unusual? O A. The sample mean would be considered unusual because there is a probability less than 0.05 of the sample mean being within this range. O B. The sample mean would be considered unusual because there is a probability greater than 0.05 of the sample mean being within this range. O C. The sample mean would not be considered unusual because there is a probability greater than 0.05 of the sample mean being within this range. O D. The sample mean would not be considered unusual because there is a probability less than 0.05 of the sample mean being within this range.
