A population of values has a normal distribution with u = 25.2 and o= 46.1. You intend to draw a random sample of size n = 80. Find the probability that a single randomly selected value is less than 25.2. P(X < 25.2) = Find the probability that a sample of size n= 80 is randomly selected with a mean less than 25.2. P(M< 25.2) = 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.
