A team of marketing research students was asked to determine the pizza best liked by students enrolled in the team's college. Two years ago a similar study was conducted, and it was found that 40% of all students at this college preferred Bellini's pizza, 25% chose Anthony's pizza as the best, 20% selected Ferrara's pizza, and the rest selected Marie's pizza. To see if preferences have changed, 180 students were randomly selected and asked to indicate their pizza preferences. The results were as follows: 40 selected Ferrara's as their favorite, 32 students chose Marie's, 80 students preferred Bellini's, and the remainder selected Anthony's. Do the data indicate that the preferences today differ from those from the last study?
