   Below you see variables in a study of physical fitness. Determine which random variable X is not a continuous variable:‖  I The subject is male or female, X = the number of female. II After every 30 minutes, a trainer comes by to whom you ask to measure your effort. X = the number of times the trainer comes by per day. III You measure the V-O₂, the maximum oxygen consumption per minute during exercise. X = the number of liters of oxygen consumption per minute.

   
   
   1. TRUE: I and II are not continuous random variables.
   2. FALSE: II and III are not continuous random variables.
   3. FALSE: I and III are not continuous random variables.
   4. FALSE: All three are not continuous random variables.
