Need help solving this

Let X represent the full length of a certain species of newt. Assume that A has a normal probability distribution with mean 47.9 inches and standard deviation 6.4 inches. You intend to measure a random sample of n = 209 newts. 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. Complete the indicated boxes, correct to two decimal places. Hz
