A Statistics teacher wants to know if students exposed to the use of technology in the classroom got significantly higher scores in Statistics exam than those who are exposed to the traditional chalk and talk method. She took a sample of 30 students exposed to technology and recorded their Statistics exam scores: 95 88 81 98 81 80 83 80 91 80 75 83 88 85 81 85 83 86 89 88 90 89 88 85 87 86 66 85 65 95She then took a sample of 40 students who were taught using the traditional method 88 78 81 87 91 90 83 84 66 81 80 74 73 71 66 60 78 78 65 60 71 85 89 79 80 83 75 73 80 71 65 71 89 81 75 60 82 80 90 83 Help the teacher verify the hypothesis at α = 0.05.
