    SPRING 2013

    FINAL EXAMThis test is governed by UFs academic honesty code. It is intended to have 33

    multiple choice questions. Please check to be sure your copy has all 33. Choose

    the best answer for each question.

    The next is important: Unless you are specifically told otherwise, on this test do

    notassume that demand or supply is either perfectly elastic or perfectly inelastic.

    On the bubble sheet, please enter:

    1. Your name and initials

    2. Your UF ID number

    3. Form code: A

    4. Sign your name on the bubble sheet.

    TURN OFF ALL CELL PHONES AND OTHER

    COMMUNICATION DEVICES

    Check that the form code and UF ID number you bubbled-in are correct now. Also check

    to be sure your name is correctdo it now. I investigated the rumor that the ability to

    correctly record these had been mastered by a few students at FSU. This rumor turned

    out to be false. But, the rumor that an accounting major and a journalism major did

    successfully record these on a test is true. These students have since been bronzed and

    are on display outside their respective colleges to serve as an inspiration for all other

    accounting and journalism students.CHECK YOUR FORM CODE AND UF ID NUMBER. IF YOU GET EITHER OF THESE

    WRONG, YOUR TEST MIGHT NOT BE GRADED AND IF IT IS GRADED, YOU WILL

    LOSE 6 POINTS (which equals 2 questions)!

    I have become increasingly concerned that some students are at a real disadvantage

    because they are unwilling to ask questions during the exam while others ask a lot of

    questions. Hence, to level the playing field, I have decided to eliminate allquestions

    during the test. I dont like this policy, but it seems the fairest policy.

    Do not ask questions of me or the TAs; in the interest of fairness I

    have instructed them not to answer any questions during the exam.

    You will have one hour (60 minutes) to complete the exam andbubble in all youranswers. When the TAs say that time is up, you musthand in your exam. We will not

    give extra time to finish bubbling in the answers, so be sure you are done when the 60

    minutes are up. Of course, you may hand in your test at any time before the 60 minutes

    are up.
