Suppose that the mean cranial capacity for men is 1040 cc (cubic centimeters) and that the standard deviation is 300 cc. Assuming that men's cranial capacities are normally distributed, complete the following statements. (a) Approximately 68% of men have cranial capacities between cc and cc. (b) Approximately ? 1940 cc. of men have cranial capacities between 140 cc and X D B Suppose that the mean cranial capacity for men is 1040 cc (cubic centimeters) and that the standard deviation is 300 cc.
