Central Limit Theorem: Finding Probability
A population of values has a normal distribution with μ=197.5 and σ=40.9. You intend to draw a random sample of size n=188.
a.) Find the probability that a single randomly selected value is between 190.9 and 204.4.
P(190.9 < X < 204.4) = (Round to 4 decimal places.)
b.) Find the probability that a sample of size n=188n=188 is randomly selected with a mean between 190.9 and 204.4.
P(190.9 < M < 204.4) = (Round to 4 decimal places.)
