WHAT IS THE MEAN FOR MY DATA

Answer 1

82.41

Explanation:

In this, you have to add all of them together such as...

71 + 73 + 77 + 82 + 88 + 91 + 92 + 92 + 89 + 84 + 78 + 72 you add all of the numbers together not the month. Once you add you then get your great total of 989. Then count how many you have which is 12. So that means you divide 989 by 12. 989 divided by 12 = 82.4166666667. That's it. Sorry if I get this wrong I am only in elementary.

Answer 2

Answer: 82.4167 (approximate)

Explanation

Given data set = {71,73,77,82,88,91,92,92,89,84,78,72}

Add up the values:

71+73+77+82+88+91+92+92+89+84+78+72 = 989

Divide that sum by the sample size 12 to get the sample mean.

989/12 = 82.416666.... where the 6's go on forever.

If we round to say 4 decimal places, then we get 82.4167. Round this however your teacher instructs.
