1. What is the probability of obtaining a test score above 92 for a distribution with a M= 71 and an SD = 5.50 (try drawing out a normal curve with the values you need to find if you're struggling)? (3pts)

a. First compute the z-score for a score of 90 by completing the transformation equation

below:

z = (x - M) / SD

z =

z =

b. Now look in Appendix B of your textbook for the z-score you obtained. You need to figure out the probability of getting above 92. Think about what is to the left of the mean on a standard normal distribution for help.

Area b/t the mean and the z-score =

Area to the right of the mean total =

Probability of obtaining an 90 or above =
