The average score on a standardized test is 500 points with a standard deviation of 50 points. if 2000 students take the test at a local school, how many students do you expect to score between 500 and 600 points

954 students.      

Step-by-step explanation:

We have been given that the average score on a standardized test is 500 points with a standard deviation of 50 points.

To find the number of students that will score between 500 and 600 we will find z-score of 500 and 600.

Now let us find z-score for 600.

From normal distribution table we will get,

Let us find the number of students that will score between 500 and 600 by multiplying 0.4772 by 2000.

Therefore, 954 students out of 2000 students will score between 500 and 600 points.
