Suppose we have selected a random sample of n = 36 observations from a population with mean

Question:

Suppose we have selected a random sample of n = 36 observations from a population with mean equal to 80 and standard deviation equal to 6. It is known that the population is not extremely skewed.

a. Sketch the relative frequency distributions for the population and for the sampling distribution of the sample mean, x̄.

b. Find the probability that x̄ will be larger than 82.
