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, 15 had received a parking ticket. Of the 30 students who did not commute to school by car, 11 had received a parking ticket.

a.) Find the risk of having ever received a parking ticket for students who commuted by car and the risk for those who did not commute by car. (Round your answers to three decimal places.)

b.) Find the relative risk of receiving a parking ticket for those who commuted by car and those who did not. (Put the group with lower risk in the denominator. Round your answer to three decimal places.)
