In a sample of 200 UM students, 170 students reported listening
to Eminem daily. In a similar sample of 150
OSU students, 107 students reported listening to Lizzo daily.
a. Do the same proportion of UM and OSU students listen to Lizzo
every day? Test at 98% confidence
b. If you want to create a 90% confidence interval with a margin of
error of .09, and want to include 1.5
times as many OSU students as UM students, how many people do you
need from each school?
