PASSAGE
A university dining hall manager tracks student meal preferences over a semester. She initially models student choices assuming each of the five meal options (pizza, salad, sandwich, soup, pasta) has equal probability of being selected.
After collecting data for 1000 student meals, the manager finds: pizza chosen 320 times, salad chosen 180 times, sandwich chosen 220 times, soup chosen 80 times, and pasta chosen 200 times. She also notices that pizza is chosen 45% of the time on Fridays but only 25% of the time on Mondays. Which conclusion about the equal probability model is most appropriate?
