The graphing calculator command shown in Figure A generated a set of 400 random integers from 2 to 24, stored as list L₁. The statistical plot in Figure B is a histogram of L₁, 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 4, starting at 1.5.

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