An experiment consists of rolling a pair of dodecahedral (12-sided) dice and recording their sum (the sides of each die are numbered from 1 to 12). The command shown in Figure A simulated 500 rolls of the dodecahedral dice. The statistical plot in Figure B is a histogram of the 500 sums using a class interval width of 1, starting at 1.5.

(A) Explain how the window variables can be changed to display a histogram of the same data set using a class interval width of 2, starting at 1.5. A width of 3, starting at -0.5.

(B) Describe the effect of increasing the class interval width on the shape of the histogram.
