Answer to Question 1

FALSE

Answer to Question 2

The value 548 is two standard deviations above the mean; hence the Empirical Rule implies that the area between the mean and 548 is approximately 0.95 / 2 = 0.475. Therefore the proportion of the observations less than 548 is approximately 0.975.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
