(B) Approximately 95% of the sample population would be expected to have a CO between 3 and 7 L/min
(C) Ten of the sample patients have a cardiac output greater than 5 L/min
(D) The mean and the median are both at the 50th percentile
(E) The median and the mode are the same in the sample population
