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 45.7 minutes and the standard deviation was 63.3 minutes. For the sample of females, the mean time spent using a computer was 39.5 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 a = 0.05. (Use males - Hemales:) A USE SALT Find the test statistic. (Round your answer to one decimal place.) t= Find the df. (Round your answer down to the nearest whole number.) df = Find the P-value. (Round your answer to three decimal places.) P-value = State your conclusion. O Reject Ha. 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. O Reject Hg. We have convincing evidence that the mean time per day male students at this university spend using a computer greater than the mean time for female students. O Fail to reject Hg. 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. O Fail to reject Ha. 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.
