3. In a study of factors that affect whether students return to college after the first semester, one of the factors examined was the number of hours worked per week. The analysis revealed that students typically work an average of 18.1 hours per week, with a standard deviation of 15.3 hours. If we consider a group of 700 freshmen at a community college, what is the probability that the average number of hours worked per week is more than 20 hours?
