Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with mean 137.9 ft and standard deviation 49.5 ft. You intend to measure a random sample of n = 153 trees. The bell curve below repręsents the distribution of these sample means. The scale on the horizontal axis is the standard error (standard deviation) of the sampling distribution. Complete the indicated boxes, correct to two decimal places.
