Question
In a clinical trial of a certain drug, 17 subjects experience headaches among the 222 subjects treated with the drug. Construct a 90% (Wald) confidence interval estimate for the proportion of treated subjects who experience headaches, completing parts (a) through (d) below.
a. Find the best point estimate of the population proportion.
(Type an integer or a decimal rounded to three decimal places
b. Identify the value of the margin of error E.
needed.)
Type an integer or a decimal rounded to three decimal places as needed.)
c. Construct the confidence interval.
0<P<0
(Round to three decimal places as needed.)
d. Write a statement that correctly interprets the confidence interval.
Select the correct choice below and fill in the answer box to complete your choice.
(Type an integer or a decimal. Do not round.)
O A. We have % confidence that the true value of the population proportion of subjects treated with the drug who experience headaches actually is between the confidence interval's lower and upper limits.
O B. % of sample proportions will fall between the lower and upper limits of the confidence interval.
OC. There is a
O D. We have
% chance that the true value of the population proportion of subjects treated with the drug who experience headaches will fall between the confidence interval's lower and upper limits.
% confidence that the true value of the sample proportion of subjects treated with the drug who experience headaches actually is between the confidence interval's lower and upper limits.
