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
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
