Calculating Standard Error of the Mean
A tree farmer wants to estimate the average height of the
spruce tree saplings that are growing on the farm. The
distribution of heights of all tree saplings on the farm is
approximately Normal. The farmer selects a random
sample of 18 trees and measures their heights. The
average height of the trees is 12.4 inches with a standard
deviation of 1.8 inches.
