An athletic coach conducted an experiment to test whether a four week strength training program will reduce the number of muscular injuries that occur during athletic events. The coach randomly selected 30 athletes from several sports and assigned 15 athletes to a four week strength training program. The remaining 15 athletes did not participate in any type of strength training program during the four weeks of the program.

After the program was completed, the coach monitored each of the 30 athletes for five athletic events. At the end of this process, he reported that the average number of muscular injuries for athletes enrolled in the strength training program is equal to the average number of muscular injuries for athletes not enrolled in the strength training program.

What can be concluded from the coach's report?

A.

It can be concluded that the strength training program increases the number of muscular injuries that occur during an athletic event.
 

B.

It can be concluded that the strength training program reduces the number of muscular injuries that occur during an athletic event.
 

C.

It can be concluded that the strength training program does not reduce the number of muscular injuries that occur during an athletic event.
 

D.

There is not enough information to make any conclusions regarding the coach's report.

I am pretty sure the answer is C. It is true that the strength training program does not reduce or increase the number of muscular injuries that occur during an athletic event. Since the injuries stay the same, the numbers do not reduce, so the answer is C.

 

But since the average of the 5 athletic events was taken, there could be more injuries in one event, so the answer D could also be considered, but I think the correct answer would be C.
