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 45.8 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 μmales „females' 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 = State your conclusion. ◇ Reject Ho. We do not have convincing evidence that the mean time per day male students at this university spend using a computer is greater than the mean time for female students. ○ Fail to reject Ho. We have convincing evidence that the mean time per day male students at this university spend using a computer is greater than the mean time for female students. Fail to reject Ho. We do not have convincing evidence that the mean time per day male students at this university spend using a computer is greater than the mean time for female students. Reject Ho. We have convincing evidence that the mean time per day male students at this university spend using a computer is greater than the mean time for female students.
