Barone's Italian Restaurant advertises that its customers are much happier than the customers of its main competitors. The claim is based on the results of a customer satisfaction survey shown in the graph below. Which statement best describes why the graph is misleading? Restaurant Satisfaction Rating Barone's Fertello's Dibiasi's 82% 86% 90% Customer Satisfaction OA Not enough restaurants were included in the survey. OB Barone's rating looks better than it really is because the graph does not start at 0. OC It is difficult to determine the actual satisfaction levels for each restaurant, so a clear comparison cannot be made. OD Using percentages makes it seem like there is a large difference in customer satisfaction between Barone's and its competitors. 6. What was the most common amount of time spent studying?
