Chapter CSB1.14, Problem 7E

To determine

To determine which kind of graph can display the given data in the best way.

Answer to Problem 7E

Double line graph

Explanation of Solution

Given:The prices of lawn seats at events held at an amphitheater is given in dollars below.

23	29	31	34	19	28	35	37
22	28	26	33	35	39	26	27

Here, change in the price of the seat is to be displayed for the two rows. So, the double line graph would be most suitable for this condition. The difference in the price of the seats can be judged by looking at the change in the slope of the lines in the graph. And the difference between the prices of the seats of the two rows can be judged by looking at the relative positions of that line for the specific points or the seats.
