A population of values has a normal distribution with μ = 161.2 and σ = 4.9 . You intend to draw a random sample of size n = 220 . Find the probability that a single randomly selected value is between 160.6 and 161.8. P(160.6 < X < 161.8) = 5.184 Incorrect Find the probability that a sample of size n = 220 is randomly selected with a mean between 160.6 and 161.8. P(160.6 < M < 161.8) = .9307...
