Let X represent the full height of a certain species of tree. Assume that X has a normal probability distribution with u = 110.4 ft and o = 46.4 ft. You intend to measure a random sample of n = 219 trees. What is the mean of the distribution of sample means? What is the standard deviation of the distribution of sample means (i.e., the standard error in estimating the mean)? (Report answer accurate to 2 decimal places.)
