A population of values has a normal distribution with =216.9=216.9 and =47=47. You intend to draw a random sample of size n=157n=157. Find the probability that a single randomly selected value is between 221.8 and 225.2. P(221.8 < X < 225.2) = Find the probability that a sample of size n=157n=157 is randomly selected with a mean between 221.8 and 225.2. P(221.8 < M < 225.2) = 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.
