Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with mean 71.5 ft and standard deviation 51.4 ft. You intend to measure a random sample of n = 41 trees. The bell curve below represents the distibution of these sample means. The scale on the horizontal axis is the standard error of the sampling distribution.
