Each year, a Freshman English teacher surveys her incoming students about their stress level on their first day of classes on a 1 (not at all) to 5 (extremely stressed) scaled. They are particularly interested in how this year's data, impacted by COVID-19, compares to what was collected this time last year. Assuming that the mean of last year's incoming Freshman class was 3, how many people responded above that this year?
