# College mathematics instructors suggest that students spend 2 hours outside of class studying for every hour in class. so, for a 4 credit math class students should spend at least 8 hours (480 minutes) studying each week. the given data represent the time spent on task recorded on mymathlab (in minutes) for randomly selected students during the third week of the semester. determine if the evidence suggests that students are studying less than 480 minutes per week. use a 0.1 level of significance and report an appropriate confidence interval for the population parameter. 509 438 485 449 478 492 460 485 477 484 499 493 469 459 500 471 482 444 472 471 463 472 471 475 473
