Using the American Hospital Association database, determine the number of hospitals in this database that are investor-owned for- profit. (Hint: In Control, 5 = investor-owned for-profit.) From this number, calculate p, the proportion of hospitals that are for-profit. American Hospital Association database Using this value of p and the binomial distribution, determine the probability of randomly selecting 15 hospitals from this database and getting more than 6 that are for-profit. (Round answer to 6 decimal places, e.g. 0.251386.) Suppose that at a large hospital, the average arrival rate of patients to the emergency room is 5.9 patients per hour during evening hours (7 p.m. to midnight). Based on that, what percentage of the time would fewer than 4 patients arrive in one hour? (Round answer to 6 decimal places, e.g. 0.251386.) What percentage of the time would more than 8 patients arrive in one hour? (Round answer to 6 decimal places, e.g. O.251386.)
