Question: The Empirical Rule is based on the standardized normal distribution. a) Describe how you could use the Empirical Rule to evaluate the distribution of scores

The Empirical Rule is based on the standardized normal distribution.

a) Describe how you could use the Empirical Rule to evaluate the distribution of scores on a national test.

You are given the following information for the national test:

(1) the population mean = 450

(2) the population SD = 75

b) Second, based on the information given above, estimate the range of scores on this test. That is, estimate the low score and the high score on the test. Discuss how you arrived at your estimate for the low and the high score

c) Finally, determine where students' test scores on the national test would place them in terms of their percentile ranking. You are given the following information on test scores of three students

1. Student A scored a 600. In what percentile is this student?

2. Student B scored a 225. In what percentile is this student?

3. If a student's score placed them in the 99th percentile, estimate the student's score using whatever approach gives you a credible estimate.
