The population mean and standard deviation are given below. Find the indicated probability and determine whether the given sample mean would be considered unusual. For a sample of n = 31, find the probability of a sample mean being less than 12,750 or greater than 12,753 when μ = 12,750 and σ = 2.2 For the given sample, the probability of a sample mean being less than 12,750 or greater than 12,753 is ? (round to four decimal places as needed.) Would the given sample mean be considered unusual? _ A The sample mean would be considered unusual because there is a probability less than 0.05 of the sample being within this range _ B The sample mean would not be considered unusual because there is a probability greater than 0.05 of the sample mean within this range _ C The sample mean would be considered unusual because there is a probability greater than 0.05 of the sample mean within this range _ D The sample mean would not be considered unusual because there is a probability less than 0.05of the sample mean within this range
