Answer
Explanation:
Step1: Calculate sum of alligators
$7 + 0+11 + 10=28$
Step2: Calculate number of data - points
There are 4 bodies of water, so $n = 4$.
Step3: Calculate the mean
The formula for the mean $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$. Substituting the sum of alligators ($\sum_{i=1}^{n}x_{i}=28$) and $n = 4$ into the formula, we get $\bar{x}=\frac{28}{4}=7$.
