Question

Pete’s grade on a test was within 5 points of his class average of 94. What is his range of grades on the test?

Answer 1

I'm pretty sure it would be 89-99.

Answer 2

Answer: 89 to 99

Explanation:

We know that the range of data is given by :-

`\overline{x}\pm E`, where
`\overline{x}` ios the average of data and E is the margin of error.

Given : Margin of error =
`\pm 5`

Class average =
`94`

Then, the range of grades on the test will be :-

`94\pm 5=(94-5,\ 94+5)=(89,\ 99)`

Hence, the range of grades on the test = 89 to 99
