Q20. We want to identify PSY students who will do well in Graduate School based on their marks in PSY 2106, which happen to be normally distributed. Students with scores in the top 2% of the distribution are deemed most likely to succeed. If we have scores for 3,500 students in PSY2106, the average mark is 70, and the standard deviation is 9.5, what is the cut-off score to identify students most like] to succeed? Show our work. 9 marks
