The article "Facebook Use and Academic Performance Among College Students" (Computers in Human Behavior [2015]: 265-272) estimated that 87% percent of students at a large public university in California who are Facebook users update their status at least two times a day. Suppose that you plan to select a random sample of 400 students at your college. You will ask each student in the sample if they are a Facebook user and if they update their status at least twice a day. You plan to use the resulting data to decide if there is evidence that the proportion for your college is different from the proportion reported in the article for the college in California.
