Unformatted text preview: STAT 31 Practice Midterm 1 Spring 2004 INSTRUCTIONS: BOTH THE EXAM AND THE BUBBLE SHEET WILL BE COLLECTED. YOU MUST PRINT YOUR NAME AND SIGN THE HONOR PLEDGE ON THE BUBBLE SHEET. YOU MUST BUBBLE-IN YOUR NAME & YOUR STUDENT IDENTIFICATION NUMBER. EACH QUESTION HAS ONLY ONE CORRECT CHOICE (decimals may need rounding). USE "NUMBER 2" PENCIL ONLY - DO NOT USE INK - FILL BUBBLE COMPLETELY. NO NOTES OR REMARKS ARE ACCEPTED - DO NOT TEAR OR FOLD THE BUBBLE SHEET. A GRADE OF ZERO WILL BE ASSIGNED FOR THE ENTIRE EXAM IF THE BUBBLE SHEET IS NOT FILLED OUT ACCORDING TO THE ABOVE INSTRUCTIONS. QUESTIONS ARE WORTH ONE POINT EACH.

By no means you should consider these as a complete set of questions that might appear on the exam. Suggestion: Look at the questions, work on them first WITHOUT using the answer keys. Look through the textbook to help you solve those questions you can not solve. Final, look at the answer keys to help you solve those still-unsolved questions. The final final step is to ask for help from fellow students or the instructor. Good Luck! 1.
