100 professional players qualified to take part in the World Cup for a video game.
In each round, players were awarded points based on their position.
The overall positions in the tournament were determined by the total number of points
that the players scored from all the rounds. The winning player gained the highest
number of final points.
Keito believes that professional players from countries in Asia are better players than
those from other continents.
To test this belief, he obtained a sample of 20 players from those in the World Cup.
The final points of the players are shown in Figure 1.
