To find the mean of a data set, you add up all the numbers and then divide by the count of the numbers. Let's find the mean of the data set 143, 117, 151, 156, 310, 115, and 128:
1. Add up all the numbers:
\[
143 + 117 + 151 + 156 + 310 + 115 + 128 = 1120
\]
2. Count the numbers in the data set:
\[
\text{There are 7 numbers.}
\]
3. Divide the sum by the count of the numbers:
\[
\text{Mean} = \frac{1120}{7} = 160
\]
So, the mean of the data set is 160.
