A population of values has a normal distribution with =126.1 and =26.8. You intend to draw a random sample of size n=18. Find the probability that a single randomly selected value is less than 122.9. P(X < 122.9) = Find the probability that a sample of size n=18 is randomly selected with a mean less than 122.9. P(M < 122.9) = 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..
