Answer to Question 1

The value 572 is three standard deviations above the mean; hence the Empirical Rule implies that the area between the mean and 572 is approximately 1.00 / 2 = 0.50. Therefore the proportion of the observations greater than 572 is approximately 0.0.

Answer to Question 2

FALSE
