The parallel dotplots below display the number of hours spent studying for a final exam by each of two classes. 2 dotplots titled hours spent studying by class. The number lines go from 0 to 6 and are labeled number of hours. For statistics, 0, 1; 1, 0; 2, 5; 3, 6; 4, 5; 5, 0; 6, 1. For Calculus, 0, 5; 1, 2; 2, 2; 3, 1; 4, 2; 5, 1; 6, 5.

Which of the following is a true statement?

The range for the distribution of the number of hours spent studying for calculus is larger.
The range for the distribution of the number of hours spent studying for statistics is larger.
There is a larger standard deviation in the distribution of the number of hours spent studying for calculus.
The standard deviation for the distributions of number of hours spent studying is the same for both classes.
