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=70, the probability of a sample mean being greater than 224 if u=223 and o=5.7 is? Would the given sample mean be considered unusual? The sample mean would/would not be considered unusual because it does/does not lie within a range of usual event.
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=70, find the probability of a sample mean being greater than 211 if p = 210 and 6 = 3.5.
