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 230 if =229 and =3.5.

For a sample of n=70, the probability of a sample mean being greater than 230 if =229 and =3.5 is
