Answer to Question 1

b
RATIONALE: The coefficient of variation indicates how large the standard deviation is relative to the mean. The coefficient of variation is (6.75/31.6  100) = 21.36.

Answer to Question 2

d
RATIONALE: The standard deviation is defined to be the positive square root of the variance and can be calculated using the Excel function = STDEV.S( ).
