Question:
Do male college students spend more time studying than female college students? This was one of the questions investigated by the authors of the paper “An Ecological Momentary Assessment of the Physical Activity and Sedentary Behaviour Patterns of University Students” (Heath Education Journal [2010]: 116–125). Each student in a random sample of 46 male students at a university in England and each student in a random sample of 38 female students from the same university kept a diary of how he or she spent time over a 3-week period. For the sample of males, the mean time spent studying per day was 280.0 minutes, and the standard deviation was 160.4 minutes. For the sample of females, the mean time spent studying per day was 184.8 minutes, and the standard deviation was 166.4 minutes. Is there convincing evidence that the mean time male students at this university spend studying is greater than the mean time for female students? Test the appropriate hypotheses using α = 0.05.
