7. Brenda is the owner of Brenda's Hair Salon. She produced the following graph to show that her customers are more satisfied than customers of two nearby salons owned by Nancy and Tammy. Which statement best describes why the graph is misleading? Salon Satisfaction Rating Nancy's Tammy's Brenda's 85% 90% 95% Customer Satisfaction It is difficult to determine the actual satisfaction levels for each salon, so a clear comparison cannot be made. Brenda's ratings look better than they really are because the graph does not start at zero. Using percentages makes it seem like there is a large difference in customer satisfaction between Brenda's Hair Salon and its competitors. Not enough salons were included in the survey.
