Do male college students spend more time than female college students using a computer? This was one of the questions investigated by the authors of an article. 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 three-week period.

For the sample of males, the mean time spent using a computer per day was 45.6 minutes and the standard deviation was 63.3 minutes. For the sample of females, the mean time spent using a computer was 39.3 minutes and the standard deviation was 57.3 minutes. Is there convincing evidence that the mean time male students at this university spend using a computer is greater than the mean time for female students? Test the appropriate hypotheses using

α = 0.05.

(Use a statistical computer package to calculate the P-value. Use μmalesμfemales.Round your test statistic to two decimal places, your df down to the nearest whole number, and your P-value to three decimal places.)

 t = df = P-value =
