A statistical experiment is carried out on 30 male rats. 15 of the rats, chosen at random, are given an energy drink, while the other 15 rats maintain their usual diet. All of the rats then run through a maze. The rats who had the energy drink run the maze in a mean time of 37.2 seconds, while the rats who did not have the energy drink run the maze in a mean time of 41.3 seconds.

Are the numbers 37.2 and 41.3 parameters or statistics?

a) 37.2 is a statistic and 41.3 is a parameter.

b) 37.2 is a parameter and 41.3 is a statistic.

c) 37.2 and 41.3 are both statistics.

d) 37.2 and 41.3 are both parameters.
