You are given a contingency table laying out the success and failure amounts of various treatments for a disease.

You wish to test the following claim that success of the treatment is independent of the type of treatment.

Which of the following would be your hypotheses?

A.) H 0 : The proportion of success is the same in each treatment. H 1 : The proportion of success is NOT the same in each treatment.

B.) H 0 : Success is independent of treatment. H 1 : Success and treatment are dependent.

C.) H 0 : The proportion of success is NOT the same in each treatment. H 1 : The proportion of success is the same in each treatment.

D.) H 0 : Success and treatment are dependent. H 1 : Success is independent of treatment.

You wish to test the following claim: A population of weights has the last digit (ones-digit) that do NOT occur with the same frequency.

Which of the following would be your hypotheses?

A.) H0:H0:The proportion of each digit occuring is the same.
H1:H1:The proportion of each digit occuring is NOT the same.

B.) H0:H0:The proportion of each digit occuring is NOT the same.
H1:H1:The proportion of each digit occuring is the same.

C.)H0:H0:Proportion is not independent of digit.
H1:H1:Proportion is independent of digit.

D.) H0:H0:Proportion is independent of digit.
H1:H1:Proportion is not independent of digit.
