In studying basal areas of similar trees for many years, a scientist has discovered that these measurements (in square inches) are normally distributed with standard deviation approximately 4 square inches. If the forester samples n = 9 trees, find the probability that the sample mean will be within 2 square inches of the population mean. Note: Please round your answer to 4 decimal places.
