Three hundred tenured professors at Florida Universities are randomly sampled and are asked: “On what day of the week were you born?” The results are in the table below. Assuming that each weekday has an equal theoretical probability, which day of the week has the most unusual observed frequency in this sample?

Day Sun Mon Tue Wed Thu Fri Sat
Count 36 42 60 42 57 30 33

Sunday


Wednesday


Tuesday


Friday

Tuesday has the most unusual observed frequency in this sample, as it has the highest count of 60 compared to the expected theoretical probability of 44.29 (310/7 = 44.29).
