The variance of 73 72 67 74 78 84 79 71 76 76 79 81 75 80 78 76 78 = 16.8456
The sum of 622 and 84 is 706.
68+84=148 ------> 148/2=74 74 is the average.

It is: 84/74 times 100 = 113.5% rounded to one decimal place
1 + 5 + 13 + 65 = 84
67, 71, 73, 79 and 83.
If the average of 5 numbers is 86, then their sum is 430.If the average of 6 numbers is 84, then their sum is 504.The sum grew by (504 - 430) = 74, so that was the 6th number.
98-56 = 42

The sum of 622 and 84 is 706.
average of 71%, 84% and 90% = 81.67% = (71% + 84% + 90%)/3 = 245%/3 = 81.67%
68+84=148 ------> 148/2=74 74 is the average.
