A random sample X1, X2,..., X9 is selected from a normal distribution with mean
μ and variance σ^2 . Let X and S^2 be the mean and variance of the sample.
a) The probability P(X > μ +σ ) is between ?
b) The probability P(X > μ + S) is between ?
How would you solve these?
n=9, but we are not given any other information,
