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 responses are displayed in the table.   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. What is the appropriate inference procedure? chi-square test for goodness of fit because the data come from one random sample chi-square test for homogeneity because the data come from independent random samples chi-square test for association/independence because the data come from one random sample chi-square test for association/independence because the data come from independent random samples
