Answer to Question 1

FALSE

Answer to Question 2

The values 428 and 572 are within  three standard deviations of the mean; hence the Empirical Rule implies that the proportion of the observations between these two values is approximately 1.0. That is, almost all the observations are contained between 428 and 572.
