What is the mean of this data set? If necessary, round your answer to the

nearest tenth.

12, 16, 22, 23, 34, 44, 46, 47, 48, 64, 67, 73, 83, 88, 89

Answer: 50.4

Step-by-step explanation: The mean of a data set is equal to the sum of the set of numbers divided by how many number are in the set.

So to find the mean of the data set shown here, let's begin by adding the numbers.

12 + 16 + 22 + 23 + 34 + 44 + 46 + 47 + 48 + 64 + 67 + 73 + 83 + 88 + 89 = 756

756 will be divided by how many numbers are in the set which is 15 which gives us 50.4.

50.4 is already rounded to the nearest tenth.

50.4

Step-by-step explanation:

First, add the values. You will get 756. The you divide the sum by the number of data values, which is 15. You will end up with 50.4
