Question

What is the mean for the data set, to the nearest whole number?

A. 8.5

B. 10

C. 9

D. 8

Answer 1

Given the set 5, 8, 8, 8, 8, 9, 9, 9, 10, & 10. Calculate the mean which is the average of a given data set.

`\bold{Mean}=(Sum \ of \ all \ Data \ Points )/(The \ Amount \ of \ Data \ Points \ you \ have)`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`\bold{Mean}=(5+8+8+8+8+9+9+10+10 )/(10)`

`\Longrightarrow \bold{Mean}=(75 )/(10)`

`\Longrightarrow \bold{Mean}=7.5`

`\Longrightarrow \boxed{\bold{Mean} \approx 8} \therefore Sol.`
