A population of values has a normal distribution with μ=165.6 and σ=84.7. You intend to draw a random sample of size n=59. Find the probability that a single randomly selected value is between 133.6 and 146.9. P(133.6 < X < 146.9) = Find the probability that a sample of size n=59 is randomly selected with a mean between 133.6 and 146.9. P(133.6 < M < 146.9) = 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.
