A population of values has a normal distribution with u = 193.7 and o = 14.4. You intend to draw a random sample of size n = 19. Find the probability that a single randomly selected value is greater than 189.4. P(X > 189.4) = Find the probability that a sample of size n = 19 is randomly selected with a mean greater than 189.4. P(M > 189.4) = 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.
