It never hurts to get a bit more practice. So this is problem number five from the normal distribution chapter from ck12.org's AP Statistics Flexbook. So they're saying the 2007 AP Statistics examination scores were not normally distributed with a mean of 2.8 and a standard deviation of 1.34. They cite some College Board stuff here. I didn't copy and paste that. What is the approximate z-score? Remember, z-score is just how many standard deviations you are away from the mean.
