Answer 1

The answer is C. 83.3

Answer 2

Answer: c. 83.3

Explanation:

The given data set ={79, 42, 86, 103, 79, 111}

We know that the mean of a data set is given by :-

`\text{Mean}=\frac{\text{sum of all elements in the data set }}{\text{number of all elements in the data set}}`

`\Rightarrow\ \text{Mean}=(79+42+86+103+79+111)/(6)\\\\\Rightarrow\text{Mean}=(500)/(6)\\\Rightarrow\text{Mean}=83.3333\approx83.3`

Hence, the mean of the given data set = 83.3
