Suppose that the distribution of scores on the Graduate Record Exam (GRE) is approximately normal, with a mean of p = 150 and a standard deviation of o = 5. Using the Distributions tool, answer the questions that follow for the population of students who have taken the GRE: Standard Normal Distribution Lean00 Standard Deviation - 1.0 .5000 .5000 -1.0 -0.5 0.5 1.0 1.5 2.0 0.0 0.00 z What proportion have GRE scores less than 145? (Round the p value to four decimal places.) p= What proportion have GRE scores greater than 1572 (Round the p value to four decimal places.) P= What is the minimum GRE score needed to be in the highest 20% of the population? X = If a graduate school accepts only students from the top 10% of the GRE distribution, what is the minimum GRE score needed to be accepted? X =
