B) Very that the requirements for constructing a confidence interval are satisfied.

a) Yes, they are satisfied.

b) No, the requirement that each trial be independent is not satisfied.

c) No, the requirement that np-hat(1-p-hat) is greater than 10 is not satisfied.

d) No, the requirement that the sample size is no more than 5% of the population is not satisfied.

C) Construct a 95% confidence interval for the population proportion of patients who receive the drug and report headache as a side-effect. The 95% confidence interval is (__,__)

D) Interpret the confidence interval. Which statement bests interprets the interval?

a) We are 95% confident that the interval contains the true value of p.

b) We are 95% confident that the interval does not contain the true value of p.

c) There is a 95% chance that the true value of p will fall in the interval.
