Question 1196411: Suppose the average length of stay in a chronic disease hospital of a certain type of patient is 60 days with a standard deviation of 15. If it is reasonable to assume an approximately normal distribution of lengths of stay,
Find the probability that a randomly selected patient from this group will have a length of stay: a) Greater than 70 days b) Less than 40 days
