Question

A population of values has a normal distribution with μ = 21.9 μ = 21.9 and σ = 47.4 σ = 47.4 . You intend to draw a random sample of size n = 96 n = 96 . Find the probability that a single randomly selected value is between 12.7 and 20.4. P(12.7 < X < 20.4) = Find the probability that a sample of size n = 96 n = 96 is randomly selected with a mean between 12.7 and 20.4. P(12.7 < M < 20.4) = 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.
