Most common score = mode = 70

11. 68 (median is the score of the game in the middle of all the games in numerical order)

12. 75%; 3rd quartile is 75% of the games, and it's given as 75

13. 8%; 92% of games score 88 or less 1-92%=8%

14. 20 times mean of 72 = 1440

15. Mean of 72 +1.5(standard deviation of 11)=88.5 

16. Mean of 72 - standard deviation 11 = 61
