A random sample of n = 25 is selected from a normal population with mean μ = 101 and standard deviation σ = 13.

(a) Find the probability that x exceeds 108. (Round your answer to four decimal places.)

(b) Find the probability that the sample mean deviates from the population mean μ = 101 by no more than 3. (Round your answer to four decimal places.)
