Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many numbers are in the set.
So to find the mean of the data set shown here, let's begin by adding the numbers.
31 + 29 + 33 + 37 + 33 + 38 + 43 + 40 = 284
284 will be divided by how many numbers are in the data set which is 8 so we have to divide 284 by 8.
248 ÷ 8 = 35.5
Therefore, the mean of the data set shown here is 35.5.
