11
Mark for Review

Which choice completes the text with the most logical and precise word or phrase?

The standard deviation of the number of pages read by each student in Class A is less than the standard deviation of the number of pages read by each student in Class B.

The standard deviation of the number of pages read by each student in Class A is equal to the standard deviation of the number of pages read by each student in Class B.

The standard deviation of the number of pages read by each student in Class A is greater than the standard deviation of the number of pages read by each student in Class B.

There is not enough information to compare these standard deviations.
