Ineed the answer beacuse it's due today i tried to study it but i don't get

I believe that 4 would be the mode and the mean i believe would be 5.2. four had the most x's and then i added up 2+2+3+4+4+4+4+5+5+6+6+7+7+8+8=78 and then divided 78 by 15 because that's how many numbers were added

hope that helps

7.4 is the mean of the data.

The mean is the same thing as the average. To find the mean, you add all of the values up (so in this case, 2+2+3+4+4+4+4+5+5+6+6+7+7+8+8=111) then you divide that number by the number of numbers (I hope that made sense). Since there are 15 numbers here, we divide by 15. 111 divided by 15 = 7.4.
