It is suggested by college mathematics instructors that students spend 2 hours outside class studying for every hour in class. So, for a 4-credit-hour math class, students should spend at least 8 hours (480 minutes) studying each week. The given data, from Michael Sullivan’s College Algebra class, represent the time spent on task recorded in MyMathLab (in minutes) for randomly selected students during the third week of the semester. Determine if the evidence suggests students may not, in fact, be following the advice. That is, does the evidence suggest students are studying less than 480 minutes each week? Use α = 0.05 level of signiﬁcance.
