A questionnaire about study habits was given to a random sample of students taking a large introductory philosophy unit at Monash University. The sample of 50 students reported that they spent on average 90 minutes per week studying for the unit outside class. It was calculated that the margin of error due to sampling variation for this estimate was plus or minus 6 minutes. Therefore, we can be reasonably confident that the true average amount of time students spent studying for this unit outside class is between 84 and 96 minutes per week.
