- B B. Significance level test
- C C. Critical region test
- D D. Chi-square test
- E E. T-test
Reveal correct answer
Correct answer: D
Explanation
The correct answer is D. Chi-square test. The Chi-square test is a non-parametric statistical test that is used to compare observed frequencies in one or more categorical variables to expected frequencies. It is often used to identify categories that exhibit a pattern outside the overall average. The Null hypothesis for the Chi-square test is that there is no association between the categorical variables. The alternative hypothesis is that there is an association between the categorical variables. The Chi-square test statistic is calculated by comparing the observed frequencies to the expected frequencies. If the Chi-square test statistic is statistically significant, then it suggests that there is a statistically significant difference between the observed and expected frequencies. This suggests that there may be an association between the categorical variables. The Chi-square test can be used to identify categories that exhibit a pattern outside the overall average in a variety of situations, including:Discussion
