A population of values has a normal distribution with μ = 165.7 and σ = 4.4. You intend to draw a random sample of size n = 141. Find the probability that a sample of size n = 141 is randomly selected with a mean less than 165.4. P(M < 165.4) = Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.

A population of values has a normal distribution with μ = 50 and σ = 4.2 . You intend to draw a random sample of size n = 196 . Find the probability that a single randomly selected value is between 49.1 and 50.1. P(49.1 < X < 50.1) Find the probability that a sample of size n = 196 is randomly selected with a mean between 49.1 and 50.1. P(49.1 < M < 50.1) Enter your answers as numbers accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
