Eight people of various ages were polled and asked to estimate the number of CDs they had bought in the previous year. The following scatter plot depicts the information collected. The variable x represents the age. The variable y represents the number of CDs.. A graph has age on the x-axis, and amount of C D's on the y-axis. Points are at (18, 12), (20, 17), (24, 10), (25, 6), (28, 4), (30, 4), (32, 2), (34, 3).
Determine which table would have been used to make the scatter plot and decide if there is a linear relationship between the age of a person and the amount of CDs purchased.
