A population of values has a normal distribution with u = 180.8 and o= 9.4. You intend to draw a random sample of size n = 69. Find the probability that a single randomly selected value is greater than 179. P(X> 179) = Find the probability that a sample of size n = P(M> 179) = 69 is randomly selected with a mean greater than 179. 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.
