Question

A group of students take a Statistics Exam where the average was M = 85 and the standard
deviation was SD = 6.8. Answer the following questions regarding this distribution using your
normal curve table. Depending on the problem, be sure to identify the raw scores, Z scores,
what in particular you shaded when creating a curve and the final answer.
1. Write out your calculations.
2. Draw your normal curve- include the mean location, your score(s) location(s), and
shade the area(s) you are looking for.
3. The % from the normal curve table.
4. The final answer.
1. If you score a 99, what percentage of the population scored above you?
