Binge drinking In a recent National Survey of Drug Use and Health, 2312 of 5914 randomly selected full-time U. S. college students were classified as binge drinkers.13 (a) Calculate and interpret a 99% confidence interval for the population proportion p that are binge drinkers. (b) A newspaper article claims that 45% of full-time U. S. college students are binge drinkers. Use your result from part (a) to comment on this claim.

a) (0.374,0.406)

b) There is not enough evidence to support the claim.

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 5914

Number of binge drinkers, x = 2312

a) 99% Confidence interval:

Putting the values, we get:

b) It is claimed that 45% of students are binge drinkers. But since 0.45 does not lie in the calculated confidence interval, thus, we cannot accept the claim and 45% of full-time U.S. college students are not binge drinkers. There is not enough evidence to support the claim.
