Let $\displaystyle {X}$ represent the full height of a certain species of tree. Assume that $\displaystyle {X}$ has a normal probability distribution with mean 106.4 ft and standard deviation 8.8 ft.

You intend to measure a random sample of $\displaystyle {n}={195}$ trees. 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.
