MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Consider the following two distributions for GRE scores: N( = 150; o = 7) for the verbal part of the exam and N(u = 155; o = 7.76) for the quantitative part. Use this information to compute each of the following questions. (Round your answers to the nearest integer.) (a) The score of a student who scored in the 80th percentile on the Quantitative Reasoning section. (b) The score of a student who scored worse than 70% of the test takers in the Verbal Reasoning section. You may need to use the appropriate appendix table or technology to answer this
