Let X represent the full length of a certain species of newt. Assume that X has a normal probability distribution with mean 85.8 inches and standard deviation 3.9 inches. = 165 newts. The bell curve below represents the You intend to measure a random simple of n 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. H7 = 85. V o O, = 0.3Vo 85. Xo 85. 86. X o
