A group of students has been testing electromagnets in the lab. They made an electromagnet by wrapping copper wire around a nail. For one set of tests, they wrapped the wire around the nail 25 times. For the second set of tests, they wrapped the wire around the nail 50 times. They also have 4 different batteries: 1.5 V, 3.0 V, 4.5 V, and 6.0 V. They use their electromagnets to see how many paper clips each can pick up. For each electromagnet, two trials were conducted at each voltage. The data was recorded in the tables below.

Make a line graph of the data found above. On the same graph, show the average number of paper clips each electromagnet picked up for each voltage tested. Plot the voltage on the x-axis and the average number of paper clips picked up on the y-axis. Scale the x-axis in intervals of 1.5 volts and scale the y-axis in intervals of 5 paper clips.
