Name___________________________ Chad Hogan Winter 2010 PRACTICE First Exam Economics 101 The University of Michigan NOTES: 1. The actual exam will share the same format as this practice exam. 2. For each question, a correct answer is worth 5 points, no answer is worth 1 point, and an incorrect answer is worth 0 points. 3. Given that the exam has 30 questions, the maximum possible score is 150. 4. Given that each question has 5 possible answers, a wild guess will earn 1 point on average, the same number of points earned by providing no answer. Guessing only gives you a better return than leaving the question unanswered if you can eliminate at least one answer (in which case a guess will earn more than 1 point on average). 5. The use of calculators, cell phones, personal digital audio players, or any other electronic devices will not be permitted during the exam. 6. Have your UMID with you at all times during the exam. 7. Unless a question explicitly notes otherwise, assume that all supply and marginal cost curves slope upward and that all demand and marginal value curves slope downward.
