A population of values has a normal distribution withu = 53.9 and o = 88.4. You intend to draw a random sample of size n = 237. Find the probability that a single randomly selected value is between 44.1 and 49.3. P(44.1 X < 49.3) = Find the probability that a sample of size n 49.3. 237 is randomly selected with a mean between 44.1 and P(44.1 < M < 49.3) = 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.
