Answer: One is 95% confident that, if one were to ask all teens whether they had misrepresented their age online, between 45.6% and 52.5% of them would say they have.
Explanation:
A 95% confidence interval interprets that a person is 95% sure that the true population proportion lies in it.
Given : A research company polled a random sample of 799 US teens about internet use.
49% of those teens reported that they had misrepresented their age online to gain access to websites and online services.
The 95% confidence interval for this number is from 45.6% to 52.5%.
i.e. A per son can be 95% sure that the true proportion of all teens who admit to misrepresenting their age online is between 45.6% and 52.5%.
Correct interpretation of interval :
One is 95% confident that, if one were to ask all teens whether they had misrepresented their age online, between 45.6% and 52.5% of them would say they have.
