A population of values has a normal distribution with u = 204.1 and o = 45.9. You intend to draw a random sample of size n = 142. Find the probability that a single randomly selected value is between 209.1 and 212.2. P(209.1 < X < 212.2) = Find the probability that a sample of size n = 142 is randomly selected with a mean between 209.1 and 212.2. P(209.1 < M < 212.2) = 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.
