Question

What is correct?

A group of 80 people who had been diagnosed as prediabetic because of high blood glucose levels volunteered
to participate in a study designed to investigate the use of cinnamon to reduce blood glucose to a normal level.
Of the 80 people, 40 were randomly assigned to take a cinnamon tablet each day and the other 40 were assigned
to take a placebo each day. The people did not know which tablet they were taking. Their blood glucose levels
were measured at the end of one month. The results showed that 14 people in the cinnamon group and 10 people
in the placebo group had normal blood glucose levels. For people similar to those in the study, do the data
provide convincing statistical evidence that the proportion who would be classified as normal after one month of
taking cinnamon is greater than the proportion who would be classified as normal after one month of not taking
cinnamon?
(A) No conclusion can be made about the use of cinnamon because the people in the study were volunteers.
(B) There is convincing statistical evidence at the level of 0.01.
(C) There is convincing statistical evidence at the level of 0.05 but not at the level of 0.01.
(D) There is convincing statistical evidence at the level of 0.10 but not at the level of 0.05.
(E) There is not convincing statistical evidence at any reasonable significance level.

Sophomore, junior, and senior students at a high school will be surveyed regarding a potential increase in the extracurricular student activities fee. There are three possible responses to the survey question - agree with the increase, do not agree with the increase, or no opinion. A chi-square test will be conducted to determine whether the response to this question is independent of the class in which the student is a member. How many degrees of freedom should the chi-square test have?
