Data collected from a hospital emergency room reflect the number of patients per day that visited the emergency room due to cardiac-related symptoms.

Suppose it is believed that the number of cardiac patients entering the emergency room per day over a two-month period has a Poisson distribution with a mean of 8 patients per day.
