Answer: 89 to 99

Step-by-step 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
