Let XX represent the full height of a certain species of tree. Assume that XX has a normal probability distribution with μ=184.8ft and σ=49.8ft


You intend to measure a random sample of n=105 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)?
