A population of values has a normal distribution with M = 90.9 and σ = = 88.3. You intend to draw a random sample of size n = 175. Find the probability that a single randomly selected value is between 72.2 and 81.6. < P(72.2 X 81.6) = Find the probability that a sample of size n = 175 is randomly selected with a mean between 72.2 and 81.6. < P(72.2 M 81.6) = 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.
