Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with mean 27.7 ft and standard deviation 60.6 ft. You intend to measure a random sample of n = 139 trees. The bell curve below represents the distibution of these sample means. The scale on the horizontal axis is the standard erro of the sampling distribution. Complete the indicated boxes, correct to two decimal places. mean of distribution= standard error= Note: The left box is 2 standard errors below the mean. The middle box is the mean. The right box is 2 standard errors above the mean.
