Passing the ball between two players during a soccer game is a critical skill for the success of a team. A random sample of passes made by the English and German teams in the 2010 World Cup was drawn, and the number of successful passes in each sample was counted. Is there any difference in accuracy if we assume a level of significance of .01? See data below:

	Germany	England
# of successful passes	69	71
Total in the sample	76	91

Reject the null, there is no difference in accuracy

Do not reject the null, there is no difference in accuracy

Reject the null, there is a difference in accuracy

Do not reject the null, there is a difference in accuracy

Solutions

Expert Solution

Null hypothesis ( H₀ ) : there is no difference in accuracy

Alternative hypothesis ( H₁ ) : there any difference in accuracy

The following cross tablulation have been provided. The row and column total have been calculated and they are shown below:

	Column 1	Column 2	Total
Row 1	69	71	140
Row 2	76	91	167
Total	145	162	307

Therefore,

Do not reject the null,there is no difference in accuracy

This is a sequential game with two players A and B. In this game a dime is put on the table. A can take it or pass. If A takes a dime, the game ends; if A passes, then B can take 2 dimes or pass; if B takes 2 dimes, the game ends; if B passes, then A can take 3 dimes or pass; and so on until a choice of a dollar. This process is shown in the...

You are covering a soccer game when while heading a ball an athlete falls grabbing the back of their lower leg. You are concerned they may have strained their calf. What would the athlete complain of (symptoms) and what would you observe (signs) if they had suffered a 2nd degree strain? What are some predisposing factors that may have put the athlete at risk for this injury? For a 2nd degree strain, what positive tests would you expect to find...

1. Consider the following game. There are two piles of matches and two players. The game starts with Player 1 and thereafter the players take turns. When it is a player's turn, she can remove any number of matches from either pile. Each player is required to remove some number of matches if either pile has matches remaining, and can only remove matches from one pile at a time. Whichever player removes the last match wins the game. Winning gives...

5. Consider the following games played between two players, A and B. Game 1: A and B have reached a verbal agreement: A would deliver a case of beer to B, and B would deliver a bag of beer nuts to A. Now, each player needs to take an action: keep the promise (to deliver the goods), break the promise. If both keep their promises, then each player gets a payoff of 5; if both break their promises, then each...

This game is meant for two or more players. In the game, each player starts out with 50 points, as each player takes a turn rolling the dice; the amount generated by the dice is subtracted from the player’s points. The first player with exactly one point remaining wins. If a player’s remaining points minus the amount generated by the dice results in a value less than one, then the amount should be added to the player’s points. (As an...
