Fine the mean and range 20 14 29 39 25 19 35

First to find the mean add up all the numbers

20+14+29+39+25+19+35

which is equal to 181 now divide that number by the amount of numbers in the set, at which there are 7

So divide 181 by 7

181/7=25.86

Now round

So the mean is 26

To find the range subtract the least number from the greatest number

In which the two numbers need here are 14 and 39

39-14=15

So the range is 15
