A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Since both distributions are symmetrical, we can see that the mean of distribution X = the mean of distribution Y = 50.
Since the values in distribution X are closer to the mean than the values in distribution Y are, we can conclude that the standard deviation of distribution X is LESS THAN the standard deviation of distribution Y.
