Answer to Question 1

The mean identifies the center of the distribution and the standard deviation measures the average distance from the mean. The scores in the specific distribution would be centered around a value of 40 with most of the scores located between 36 and 44 but a few scores as much as 8 or 10 points away from 40.

Answer to Question 2

B
