Answer:
Chi-square analysis cannot be used to check for significant difference in the number of knee injuries among four sports.
Explanation:
The chi-square analysis is a statistical procedure that is used to test association between measured variables or goodness of fits of a set of measured variables to expected outcomes.
<em>In the case of testing for significant difference, chi-square analysis cannot be used as testing for significant difference in two or more means requires using t-test, analysis of variance, or any other relevant statistical procedure.</em>
To compare number of knee injuries reported among four sports for significant difference, the most suitable statistical procedure would be analysis of variance.
