A population of values has a normal distribution with μ = 154.9 and σ = 81.7. You intend to draw a random sample of size n = 12. Find the probability that a single randomly selected value is less than 178.5. P(X < 178.5) = Find the probability that a sample of size n = 12 is randomly selected with a mean less than 178.5. P(M < 178.5) = 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.
