Answer 3

If the sample is truly random, what they are trying to say is that whatever applies to the 100 people also applies to the larger population. So, they same 58% of the random 100 would also prefer art over music in the larger population of 1200.

So, .58 * 1200 = 696

So, 696 students prefer art over music.
