the numbers of regular season wins for 10 football teams in a given s 2, 9, 15, 5, 12, 8, 12, 9, 3, 7. the range is 13. (simplify your answer.) the population mean is. (simplify your answer. round to the nearest tenth as needed.)

Answer

Explanation:

Step1: Recall mean formula

The formula for the population mean $\mu=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are the data - points and $n$ is the number of data - points. Here, $n = 10$ and the data set is ${2,9,15,5,12,8,12,9,3,7}$.

Step2: Calculate the sum of data - points

$\sum_{i=1}^{10}x_{i}=2 + 9+15+5+12+8+12+9+3+7=82$.

Step3: Calculate the population mean

$\mu=\frac{82}{10}=8.2$.

Answer:

$8.2$
