Some of the questions require you to use WebStat or any of the interactivities from within CyberStats.  \nThe exam is worth a total of 200 points. The number of points for each question is indicated in parentheses at the beginning of each question. You have exactly 60 minutes to complete the exam. Try to correctly answer as many questions as possible during this time period. You are allowed to answer questions in any order. Start with a question that seems the easiest for you. If you cannot answer a question within a short time, move to another question, and come back to the previously unanswered questions toward the end of the exam.  \nObviously, you are allowed to correct your answers. However, only your last submitted answer will be graded. If you change a previously correct answer and your last submitted answer is incorrect, you will obtain 0 points for your last submitted answer.  \nNote:  \nThe actual exam will be fully given within CyberStats. This means you will have to mark your choices of multiple-choice questions and fill in answers to text-based questions within CyberStats. In the actual exam, interactivities will be directly linked to the questions. Make sure to memorize your CyberStats password for the exam.  \n1. (6 Points) A community council wishes to determine the probability that a randomly chosen driver comes to a complete stop at an intersection before proceeding through the intersection. They estimate this probability by positioning workers at several key intersections during rush hour to record whether drivers come to a complete stop or not.  \nThe number of drivers that come to a complete stop is an example of a  \na. continuous random variable  \nb. uniform distribution  \nc. normal distribution  \nd. discrete random variable  \n[e.](e. no)[ no](e. no) answer or skip this item  \n2.
