Question

A new website was reviewed by 91 people. The creator of the website surveyed 8 of the reviewers at random. He asked them to rate the website on a scale from 1 to 10. Their ratings are below.

3, 7, 10, 6, 3, 10, 10, 6

Assuming that the sample was representative of all reviewers, what was the mean rating of the website for all reviewers?
A.
4.5
B.
6.5
C.
7.125
D.
6.875

Answer 1

The mean of the number set is the average of the numbers

To find the average of the number set the numbers are to be added together and divided by the total amount of numbers in the set

$\frac{3 + 7 + 10 + 6 + 3 + 10 + 10 + 6}{8} = 6.875$
