In a survey for a statistics class project, students in the class were asked whether they commute to school by car (Yes or No) and whether they had ever received a parking ticket (Yes or No) Of the 23 students who commuted to school by car, 19 had received a parking ticket Of the 25 students who did not commute to school by car, 7 had received a parking ticket. What is the explanatory variable, and what is the response variable in this survey ? Create a contingency table for these data. Find the risk of having ever received a parking ticket for students who commuted by a car and the risk for those who did not commute by car. Find the relative risk for receiving a parking ticket for those who commuted by car and those who did not. Write a sentence giving this relative risk in words that would be understood by someone with no training in statistics. Find the odds of having receiving a ticket for students who commuted by car, and write the result in a sentence that would be understood by someone with no training in statistics.
