Suppose that the mean cranial capacity for men is 1190 cc (cubic centimeters) and that the standard deviation is 300 cc. Assuming that men's cranial capacitiesare normally distributed, complete the following statements.(a) Approximately 99.7% of men have cranial capacities between I cc and cc.(b) Approximately ?of men have cranial capacities between 590 cc and1790 cc.

Empirical rule (68-95-99.7 rule): About 68% of data lies within the one standard deviation of the…
