5. A researcher estimates that the average height of the buildings of 30 or more stories in a large city is at most 700 feet. A random sample of 10 buildings is selected and found the mean height was 606.5 feet and the standard deviation was 109.079. At a = 0.025, is there enough evidence to reject the claim?
