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, 6.0 V, 7.5 V, 9.0 V, 10.5 V, and 12.0 V. They use their electromagnets to see how many paper clips each can pick up.
For each electromagnet, three trials were conducted at each voltage. The data was recorded in the tables below. Calculate the average number of paper clips picked up (round your answer to the nearest ones).
