For many years the number of rainy days in March has been recorded in the towns of Riverton and Waterview. Riverton has a mean of 11 rainy days in March with a standard deviation of 3 days. Waterview has a mean of 13 rainy days in March, with a standard deviation of 2 days.

If the number of rainy days for both towns is graphed, Waterview’s graph will have a peak farther to the (right, left), and its peak will be (the same width, wider, narrower)
