One of the authors sometimes likes to play Minesweeper, and of the last 20 times she played Minesweeper, she won 12 times. Th at is, she won 60% of the games.
a. Based on these 20 games, we would like to learn about her long-run proportion of winning at Minesweeper. Is this value a parameter or a statistic?
b. Is 60% (12 wins in last 20 games) a parameter or a statistic?To find out whether her performance on the last 20 games provides convincing evidence that her long-run proportion of winning at Minesweeper is higher than 50%, she used the One Proportion applet to generate 100 possible values of what her number of wins could have been if her long-run proportion of winning was equal to 50%.
c. In the table below, match the aspects of the simulation performed by the applet as listed in Column A to their equivalent aspects in the actual study as listed in Column B.

Column A........................................................................................................ Column B
Coin flip.............................................................................................................Author wins a game
