A population of values has a normal distribution with μ = 180.2 and σ = 17.4 . You intend to draw a random sample of size n = 235 . Find the probability that a single randomly selected value is between 177.2 and 177.7. P(177.2 < X < 177.7) = Find the probability that a sample of size n = 235 is randomly selected with a mean between 177.2 and 177.7. P(177.2 < M < 177.7) =
