Apply the Central Limit Theorem for Sample Means Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with mean 168 ft and standard deviation 24 ft. You intend to obtain a random sample of 40 trees and compute the sample mean. The bell curve below represents the distibution of similiarly obtained sample means. The scale on the horizontal axis is the standard error of the sampling distribution. Complete the indicated boxes, correct to two decimal places.
