Me find the mean

data:
3.8
7.6
9.3
31
43
54
62
89
107
119
123
127

make sure to get the expression too

3.8+7.6+9.3+31+43+54+62+89+107+119+123+127=775.7

775.7/12=64.64166666666667

So the mean is 64.64

the answer would be 64.6416666667

this is because the mean is basically the average and to find the average you add all the numbers together and divide it by how may numbers you added together. in this case youd be dividing by 12 since there was 12 numbers.
