Answer:
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.

In order to determine the cost of each pencil we have to divide the total cost for the package of pencils by the number of pencils contained
For the 4 pencils box:
Cost per pencil = Total cost/number of pencils
Cost per pencil = 6/4 = 1.5
Similarly, for the 5 pencils package:
Cost per pencil = 7/5 = 1.4
As you can see, the $7 package is better to buy, because each pencil costs $1.4, then, option A is the correct answer
