A population of values has a normal distribution with μ = 112.1 and 87.9. You intend to draw a random sample of size n = 140. What is the mean of the distribution of sample means? t₂ == What is the standard deviation of the distribution of sample means? (Report answer accurate to 2 decimal places.) 0₂= A population of values has a normal distribution with μ = 121.5 and = 38.3. You intend to draw a random sample of size n = 33. Find the probability that a sample of size n = 33 is randomly selected with a mean between 137.5 and 140.8. P(137.5 M 140.8)= Enter your answers as numbers accurate to 4 decimal places.
