Homework Help: math

Posted by My worst subject is math on Friday, September 4, 2009 at 5:01pm.

I am a little confused on the first question of this problem could someone please check my answers and please explain why and what I need to do to get correct answer thank you

Calculate the mean, and write this as a mixed fraction.

12,9,4,6,8,12,13,14,11,5,12,2,9,13

answer I got was:132 after addition step, then second step is to divide by 15 which I got was 8.8 now I guess my confusion is do I simplify it as 88/100 = 22/25 or do I take 100 divide it by 88 which is 1 12/88? which is the correct answer

is the mean or median a more useful representative of the set?


what is (median - mean)?
I don't know this one because I am confused about question a
