Answer:
22.1666666667 ~ 22.17 (This should be rounded)
Step-by-step explanation:
The mean formula is to add all the numbers and then divide by the quantity or how many numbers were listed.
25+31+12+38+12+15/6 = mean
All the numbers added up should equal 133
You need to divide the sum by 6 since that is how many numbers that are in your data set.
The Mean of the Data set is 22.1666666667 which is approximately 22.17
