Explanation:
In mathematics, the mean of a data set is calculated by adding up all the numbers and then dividing by the number of data points. For your data set: 45, 137, 94, 173, 154, 72, 112, 94, 191, you first need to add all of these numbers together. The sum of these numbers is 1072. After finding the sum, you then divide this number by the total number of data points, which in this case is 9. So, 1072 divided by 9 equals 119.11, rounded to two decimal places. Therefore, the mean of this data set is 119.11.
