Question

A study is done on a sample of 325 people. It is determine that the proportion of people who are obese has a 95% CI of (0.316, 0.392) .

Look at the following statements and select all of them that are true.

A)If many studies were done with a sample of size 325, 95% of them would yield a confidence interval of (0.316, 0.392).

B)If many studies on samples of size 325 were performed and a confidence interval were made for each of them, 95% of these confidence intervals would include the true population proportion.

5% of the time the true population proportion of people who are obese would fall outside the range 0.316 to 0.392.

D)95% of the time, the true population proportion of people who are obese is between 0.316 and 0.392.
