567 students

#### Explanation:

If you have a graphing calculator, you can use it to find the answer!

Hit **2nd > VARS > 2: normalcdf(**

This will prompt you for the lower bound, upper bound, mean (

First, fill in your lower and upper bounds. You want to find how many students scored **between** 12 and 16. Therefore,

lower bound = 12

upper bound = 16

Fill in

Then press **paste** and **enter**, and you should get an answer of approximately .5670916759. This is the **percentage** of students who scored between 12 and 16, but we want how **many** students.

Multiply the total number of students (1,000) by the percent (.567...):

If we round down, then about **567 students** scored between a 12 and a 16.

Hope this helps! :)
