divide 910 by 11
The mean of the data set is 82.73 which is rounded to the nearest
tenth.
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
We have data set:
100, 75, 40, 90, 80, 100, 92, 88, 80, 84, 81
Mean = (sum of the observation)/number of observation
Mean = (100+75+40+90+80+100+92+88+80+84+81)/11
Mean = 910/11
= 82.727 ≈ 82.73
Thus, the mean of the data set is 82.73 which is rounded to the nearest
tenth.
