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?

Respuesta :

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

Answer: 89 to 99

Step-by-step explanation:

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

[tex]\overline{x}\pm E[/tex], where [tex]\overline{x}[/tex] ios the average of data and E is the margin of error.

Given : Margin of error = [tex]\pm 5[/tex]

Class average = [tex]94[/tex]

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

[tex]94\pm 5=(94-5,\ 94+5)=(89,\ 99)[/tex]

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