Document Summary
A sample is representative of the population as a whole. A population is any group of objects, not just people. A director needs to know how many of each of the music apps will be needed for students of the residence hall. The apps will be identified as w and j. 63 of those students showed up to vote for which app they wanted. We will then multiply this number by the total student population. Because we cannot have a fraction of a student, we can round this to 2,700. Repeat the above process to solve for how many of the total student population would want app. Reminder: our total student population is only 5,371 students. By rounding the number of students that get app w and app j to 2,700 and 2,100, respectively, we get a total of 5,400, which ensures that there will be enough apps for every student in the residence hall.
