I’m having a hard time with this. Is this a typo by the teacher or should I actually be looking for a size?
Lemur [1.5K]

Step-by-step explanation:

There are 12 games in the population.  You need to use a random number generator to choose 2 of these games.

RandomSample[{1,2,3,4,5,6,7,8,9,10,11,12},2]

Let's say the first sample you get is {1,5}.  That corresponds to game times of 8 minutes and 7 minutes.  The mean game time for that sample is 7.5 minutes.  So the first row in your table would be:

\left[\begin{array}{ccc}Sample&List\ of\ Game\ Times&Mean\ Game\ Time\\1&8,7&7.5\end{array}\right]
