1. Two students are comparing their grades on a test in two different classes. Student A’s z-score was a 1.5 on a test with an average of 75/100 and a standard deviation of 10/100. Student B’s z-score was a 4 on a test with an average of 60/100 and a standard deviation of 5/100. Who had a higher raw-score on the actual exam?

2. Is 1, the first quartile, resistant to extreme observations? Why or why not?
3. Name a variable whose distribution is likely to be symmetrical (or at least not strongly skewed). Briefly explain.
