The Columbia University Hospital wanted to know if it needed to have more than one operating room (OR) crew present during the night shift (11 p.m. to 7 a.m.)J4. If the probability that one crew is busy is greater than 1 percent, then a second OR. crew would be required. During one year, 62 patients required emergency operation during the night shift. The average operation took 80.79 minutes. Does the hospital need a second OR crew during the night shift?
