Answer 1

D.) The mean will increase

The mean is all the numbers added together than divided by the amount of numbers there, so if you do this: 4 + 6 = 10 + 16 = 26 + 15 = 41/5 = 8.2

4 + 6 = 10 + 16 = 26 + 15 = 41 + 23 = 64/6 = 10.66666666666

As you can see it increased! Hope this helped! Pls give brainiest if you can
