Question
Use the following scenario for questions #10 - 15. One of the authors of our textbook sometimes likes to play Minesweeper, and of the last 20 times she played, she won 12 times. Question 10 (1 point) Question 10 Unsaved Tell whether each of the following is a parameter or a statistic.
The long-run proportion of times the author wins at Minesweeper over many many games.
60% winning rate (12 wins in the last 20 games).
1. Parameter
2. 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%.
Match the parts of the actual study to their equivalent aspects of the simulation.
