A
The standard deviation of weight for the objects in group A is less than the standard deviation of weight for the objects in group B.
B
The standard deviation of weight for the objects in group A is equal to the standard deviation of weight for the objects in group B.
C
The standard deviation of weight for the objects in group A is greater than the standard deviation of weight for the objects in group B.
D
There is not enough information to compare the standard deviations of weight for the objects in these two groups.
