Question: A population of values has a normal distribution with = 453.3 and = 4.1. You intend to draw a random sample of size n

A population of values has a normal distribution with = 453.3 and = 4.1. You intend to draw a random sample of size n = 13. First calculate z, round it to two (2) decimal places, then use the rounded z-score to determine the required probability accurate to four (4) decimal places. 1. Find the probability that a single randomly selected value is greater than 455.8. P(x > 455.8) = 2. Find the probability that a sample of size n = 13 is randomly selected with a mean greater than 455.8. P(x > 455.8) =
