Answer

Explanation:

Step1: Find the sum of data

$8 + 12+5 + 5+0 + 15+5 + 4+5 + 2+10 + 7=78$

Step2: Count the number of data points

There are 12 data - points.

Step3: Calculate the mean

The mean $\bar{x}=\frac{\text{Sum of data}}{\text{Number of data points}}=\frac{78}{12} = 6.5$

Answer:

$6.5$
