The average age of a football player in a league is 27.

The age of 12 football players in the league are

25, 23, 26, 29, 37, 23, 32, 29, 25, 22, 31, and 34.

 

Enter the sample mean and the population mean.

 

Thanks so much !

The sample mean is the average of all the numbers in the sample. 

 

\(\frac{25+23+26+29+37+23+32+29+25+22+31+34}{12}=\frac{336}{12}=\boxed{28}\)

 

Therefore, 28 is the sample mean.

 

The population mean is the average of the whole set. 

 

This is already given in the problem, 27.

 

I hope this helped,

 

Gavin.
