Answer

Explanation:

Step1: Recall mean formula

The mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are data - points and $n$ is the number of data - points. Here $n = 10$, and the data points are $x_1=3,x_2 = 3,x_3=5,x_4 = 8,x_5=10,x_6 = 10,x_7=7,x_8 = 5,x_9=2,x_{10}=7$.

Step2: Calculate the sum of data - points

$\sum_{i = 1}^{10}x_{i}=3 + 3+5 + 8+10+10+7+5+2+7=60$.

Step3: Calculate the mean

$\bar{x}=\frac{\sum_{i = 1}^{10}x_{i}}{10}=\frac{60}{10}=6$.
