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 1201 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?

What are the null and alternative hypotheses?
O A. Ho: The two variables, educational level and diabetic state, are associated.
H₂: The two variables, educational level and diabetic state, are not associated.
O B. Ho: The variable educational level is dependent upon diabetic state.
H₂: The variable diabetic state is dependent upon educational level.
The test statistic is
(Round to three decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
