A sample of size n = 16 is to be taken from a distribution that can reasonably be assumed to be Normal with a standard deviation of 100. The null hypothesis H0 : = 500 is to be tested against the alternative hypothesis H1 : = 520.

What is the power of the .01 level test ? Pr{X > 558.159 | = 520} = P r{(558.159 520)/25 | = 520} = P r{z > 1.526} =?
