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 sp least 8 hours (480 minutes) studying each week. The given data represent the time spent on task recorded (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 x = 0.05 level of significance. Note: A normal probability plot and boxplot indicate that the data come from a population that is normally distributed with no outliers. Complete parts (a) through (e) below. Click here to view the time spent on task data. Click here to view a table of critical t-values.
