2. The data shown in the table represent the completion time (in minutes) of exams taken by two students. A. Can we conclude at the 0.10 level of significance that the average completion time of student 2 exceeds that of student 1 by 10 minutes? Assume that the distribution of times to be approximately normal with unequal variances. Also, determine the p-value. Express the p-value in the form P[_ whichever is applicable. B. Test at the 0.10 level of significance the hypothesis that of = o} against the alternative of + o}. ] =_or 2P[_ Student Time (minutes) 1 98 102 109 86 92 114 81 87 165 92 97 134
