    SUMMER A 2012

    MIDTERM 2Read all instructions on this page

    This 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 number3. Form code: A

    4. Sign your name on the bubble sheet.

    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. As I said on the last exam, I heard rumors

    that the ability to correctly record the form code has been mastered by a few students at

    FSU. I am still checking this out. But in the meanwhile a friend told me that accounting

    majors have been known to be able to record this letter, often correctly. Plus, I have

    heard of one journalism major who could get the UF ID right at least 30% of the time!

    While I doubt this last rumor, because the UF ID involves numbers which means it is

    close to being math, nonetheless I think that the skill of correctly bubbling in the formcode and UF ID is not too difficult to acquire.

    CHECK YOUR FORM CODE AND UF ID. 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 about 2 questions)!

    TURN OFF ALL CELL PHONES AND OTHER

    COMMUNICATION DEVICES

    You

    may notuse a cell phone, a Blackberry, or any other sort of device that allows forcommunication as your calculator.

    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 your

    answers. When the TAs say that time is up, you musthand in your exam. We will notgive 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.

    An answer key will be posted on the class web page later this

    evening at around 9:30 PM.

    The test scores will be on class web page within a few days.Once you see the answer key, you might have a question about why one answer

    is right and another is wrong. For these questions, email me at

    [email protected] Do NOT email the grader about these questions!

    After the scores are posted, if you think your posted score is incorrect, then email

    the grader at [email protected] If you email me about your test

    score, I will not forward the email nor respond to youyouMUSTemail the

    grader. You have one week after the curved score is posted to request a grade

    check. After a week, the score will not be changed. If the web reportswhat you

    bubbled in for each question and you ask the grader to check an answer because

    you believe you bubbled in something other than what is reported and the

    reported answer on the web is correct, you will lose 1 additional question.
