A statistics teacher taught a large introductory statistics class, with 500 students having enrolled over many years. The meanscore over all those students on the first midterm was µ = 68 with standard deviation o = 20. One year, the teacher taughta much smaller class of only 25 students. The teacher wanted to know if teaching a smaller class affected scores in any way.We can consider the small class as an SRS of the students who took the large class over the years. The average midtermscore was i = 78. The hypothesis the teacher tested was Họ : µ = 68 vs. Ha : µ # 68.The P-value for this hypothesis was found to be:0.0233.0.0124.0.0248.O 0.0062.

The test statistic is, z=x¯-μσn=78-682025=104=2.5 The test statistic is 2.5.
