Listed below are the summaries of the scores of two basketball players coming from two competing teams in the finals in the 20 games they played during the entire season. Who is the better player in terms of the scores? Player 1 Player 2 Mean 23 23 Standard Deviation 4.94 3.13 No conclusion can be made on who scores better, since the mean scores are equal. Player 2 scores better than Player 1 since Player 1 has a higher standard deviation. Player 1 scores better than Player 2 since Player 1 has a higher standard deviation. Player 1 scores better than Player 2 since Player 2 has a lower standard deviation.
