The population mean and standard deviation are given below. Find the required probability and determine whether the given sample mean would be considered unusual. For a sample of n= 66, find the probability of a sample mean being less than 24.3 if u = 24 and o = 1.29. E Click the icon to view page 1 of the standard normal table. EA Click the icon to view page 2 of the standard normal table. For a sample of n= 66, the probability of a sample mean being less than 24.3 if u = 24 and o= 1.29 is. (Round to four decimal places as needed.) Would the given sample mean be considered unusual? The sample mean V be considered unusual because it has a probability that is V than 5%.
