Samsung conducted a survey of a panel of 600 consumers and mailed them a $20 coupon for a Samsung phone. Based on the survey, Samsung determined whether each consumer currently owned a Samsung phone or not, and whether they redeemed the coupon they had received. This yielded the tabulation on the attached sheet found below. Answer this question: was the coupon more likely to attract Samsung owners or non Samsung owners? Or, was there no difference?
