RevJune 21, 2007 Instructions for Extra Credit: Pre-test With just a little effort you can get 10 points extra credit added to Public Question 1 if you: Score at least 50% on the quiz below. Pay attention to detail which is important in statistics: o Read all instructions carefully (don't wing it) o Upload the one page question sheet (last page) via the assignment in Word (no other format). The assignment is called Pretest. Due date: end of 2nd week but sooner the better. Only upload the one page answer sheet which is the last page of this document (completed) and not the questions below. Sending this by email is not acceptable since part of the test is to make sure you can upload documents (only upload the answer sheet, not the questions). I do not give extra credit after the course is over so don't miss the rare opportunity for extra credit. Extra credit can sometimes help in borderline grade cases. I do strongly urge you to complete this quiz even if you would not get the bonus of extra credit because the more important benefit to you is to make you more successful in this course by insuring you have the prerequisite math knowledge. Here is more of an explanation on the course and math: In general terms, this statistics course is about: Understanding concepts as represented by various equations. Applying these tools in business, research, and decision making. Mathematics The last bullet (the math) in my opinion is not as important as the application of statistics to solve real world problems. Of course, if you don't know basic algebra then you will have trouble with the first two \"bullets.\" You need to have taken successfully Math 107 or college Algebra.
