A sales representative for a new soft drink is trying to convince a chain of food stores to order a much larger quantity. The salesperson uses the graph below in the sales pitch. What is deceptive about the graph? A bar graph titled Sales of Mango Mango has month on the x-axis, and sales (in ten thousands) on the y-axis from 0 to 5. January, 1.9; February, 2.1; March, 3.0. a. The vertical scale needs more intervals between values. b. Sales for February and March appear to be greater than they actually are. c. Sales for January appear to be much smaller than they actually are. d. All of the above.
