A social scientist wanted to study the education levels of adults who live in the tristate area of southwestern Pennsylvania, the West Virginia panhandle, and southeastern Ohio. A random sample of 25 middle-aged adults from each region was selected and asked about their highest level of education.

The scientist would like to know if these data provide convincing evidence that the distribution of education differs for these regions in the population of all tristate residents.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 state and degree level 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 chi-square test for association/independence because the data come from independent random samples.
