Suppose a subdivision on the southwest side of Denver, Colorado, contains 1,300 houses. The subdivision was built in 1983. A sample of 100 houses is selected randomly and evaluated by an appraiser. If the mean appraised value of a house in this subdivision for all houses is $176,000, with a standard deviation of $8,400, what is the probability that the sample average is greater than $184,000?
Round the values of z to 2 decimal places. Round your answer to 4 decimal places.
