A population of values has a normal distribution with μ = 111.8 and o= 54.7. You intend to draw a random sample of size n = 118. Find the probability that a single randomly selected value is greater than 99.2. P(X> 99.2) = Find the probability that, a sample of size n = 118 is randomly selected with a mean greater than 99.2. P(M> 99.2) = 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.
