Question

A population of values has a normal distribution with μ=113.2μ=113.2 and σ=67σ=67. You intend to draw a random sample of size n=218n=218.

Find the probability that a single randomly selected value is between 100 and 125.
P(100 < X < 125) =

Find the probability that a sample of size n=218n=218 is randomly selected with a mean between 100 and 125.
P(100 < M < 125) =
