Diabetes is increasing rapidly in Native American populations. A study educational level and diabetic state are independent for Native Americans. Below is a contingency table showing cross classification of educational attainment and diabetic state for a sample of Native Americans. Use this data to determine if educational level and diabetic state are independent for Native Americans at the a = 0.10 level of significance. a) Which would be correct hypotheses for this test? O Ho: Educational level is dependent on diabetic state; H₁: Educational level and diabetic state are independent Ο Ho: μι = μ2; Hi:μι # με O Ho: Educational level and diabetic state are independent; H₁: Educational level and diabetic state are not independent Ho: p1 = P2; H₁: P1 P2

Diabetes is increasing rapidly in Native American populations. A study was done to determine if
educational level and diabetic state are independent for Native Americans. Below is a
contingency table showing cross classification of educational attainment and diabetic state for a
sample of Native Americans. Use this data to determine if educational level and diabetic state
are independent for Native Americans at the a = 0.10 level of significance.
