here we are given that in 2012 , A student earned a score of 163 on the vocabulary section of the GRE.
the mean =150 and standard deviation =13.
p(x<163)=p(x-150/13<163-150/13)
=p(z<1)
=84.13%

GRE SCORES: The test scores for the verbal reasoning and the quantitative reasoning section of the Graduate Record Examination (GRE) are normally distributed. In a recent year, the mean test score was 150 and the standard deviation was 8.75. The test score of a student is selected at random. What is the probability that the student's test score is LESS THAN 162? Round your answer to 4 decimals.
