Which data set could not be represtented by the histogram shown. {8,3,5,7,12,7,1,3,5,12}
{9,3,5,13,11,7,1,3,5,9}
{8,2,5,9,12,7,13,5,13}
{9,3,4,4,12,11,1,3,6,9}

Sorry for the delay with helping you, had to go to work.
The answer is C because the amount of kazoos needed is 1 for every student (so 26 + 24 + 30) and since 8 come in each box, you divide by 8 to get your answer of (26 + 24 + 30) ÷ 8
Hope this helped!
