Preventable chronic diseases are increasing rapidly in some regions, particularly diabetes. Shown below is a contingency table showing cross classification of educational attainment and diabetic state for a random sample of 1137 people in a region (HS is high school). At the 1% significance level, do the data provide sufficient evidence to conclude that an association exists between educational level and diabetic state for the region? Less than HS HS grad Some college College grad Total O 23 33 26 34 116 Diabetes No diabetes 233 242 404 1021 142 165 266 268 438 1137 Total ...... What are the null and alternative hypotheses? O A. H: The variable educational level is dependent upon diabetic state. H: The variable diabetic state is dependent upon educational level. O B. H: The two variables, educational level and diabetic state, are associated. H: The two variables, educational level and diabetic state, are not associated. O C. H: The two variables, educational level and diabetic state, are not associated. H: The two variables, educational level and diabetic state, are associated.
