A population of values has a normal distribution with μ=14.7μ=14.7 and σ=31.3σ=31.3. You intend to draw a random sample of size n=20n=20. Find the probability that a single randomly selected value is between 30.1 and 34.3. P(30.1 < X < 34.3) = Find the probability that a sample of size n=20n=20 is randomly selected with a mean between 30.1 and 34.3. P(30.1 < M < 34.3) = 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.
