Question

Consider these five values a population: 7, 4, 6, 4, and 7. Determine the mean of the population. (Round your answer to 1 decimal place.)

Answer 1

`Mean = 5.6`

Explanation:

Given

`7,4,6,4,7`

Required

Determine the mean

Mean is calculated as thus;

`Mean = (\sum x)/(n)`

Where n is the number of observation;

In this case;

`n = 5`

and
`\sum x` is the sum of the observations

The expression becomes

`Mean = (7+4+6+4+7)/(5)`

`Mean = (28)/(5)`

`Mean = 5.6`

Hence, the mean of the population is 5.6
