The health inspector would like to know if these data provide convincing evidence that the distribution of strep throat status differs across the departments in the population of all workers of this large company.Chi-square independence test: The chi-square is a non-parametric test which is used for comparing two categorical variables. The chi-square independence test helps in determining the relationship between categorical variables. It is used for determining whether the variables are related or not.The variables strep and department are categorical. The chi-square independence test can be used for determining relation between these two variables using the expected frequencies.Thus, the appropriate inference procedure c. chi-square test for association/independence because the data come from one random sample.
