We are 95% confident that the true proportion of young adults in the population who skip breakfast is between .20 and .27.

Step-by-step explanation:

A 95% confidence interval for the proportion of young adults who skip breakfast is .20 to .27. Which of the following is a correct interpretation of this 95% confidence interval?

We take a sample, and infer for the entire population.

So the interpretation is that we are 95% sure that the true proportion of all young adults who skip breakfast is between 0.20 and 0.27.

So the correct answer is:

We are 95% confident that the true proportion of young adults in the population who skip breakfast is between .20 and .27.
