1. Mickey Mouse and Donald Duck are extremely competitive with each other, and they want to know who did better on their exams last week. The problem is that Mickey took a Statistics exam, and Donald took a Psychology exam. Mickey got a score of X = 40 on the stats exam with M = 30 with SD = 6.25. Donald got a score of X = 73 on his psych exam with M = 62 with SD = 7.40. Who did better?

2. Intelligence (IQ) scores form a normal distribution with M = 100 and SD = 15. If a person has an IQ of 110, what % of people have higher IQs?

3. A vertical line is drawn through a normal distribution at z = -0.40. What percentage of the distribution is located between the mean and the line?
