A research firm claims that the distribution of the days of the week that people are most likely to order food for delivery is different from the distribution shown in the pie chart. You randomly select 493 people and record which day of the week each is most likely to order food for delivery. The table to the right shows the results. At a = 0.01, test the research firm's claim.
