Question: A population of values has a normal distribution with = 116.9 and = 38.2 . You intend to draw a random sample of size n

A population of values has a normal distribution with = 116.9 and = 38.2 . You intend to draw a random sample of size n = 172 .

  1. Find the probability that a single randomly selected value is between 111.9 and 124.2.
  2. Find the probability that a sample of size n = 172 is randomly selected with a mean between 111.9 and 124.2
