1. The mean for the first data set is 58 in and for the second data set, 32 set. The difference between the two means is 58-32 = 26 in
2. The means in School A is generally smaller than the medians. The opposite holds true for School B.<span />
Well, if you mean 62 tens, then it would be 620, because when you have a number times 10, you just have to add 0 to the end of the number.

If you want to find the answer just divide the 20 by the 24, then multiply by 100 to get your percentage.
20 ÷ 24 = 0.83
0.83 × 100 = 83%
