Question

the graduate record exam (gre) is a standardized test which serves as an admission requirement for many graduate schools, and has an analytic writing section and two multiple choice sections: verbal reasoning and quantitative reasoning. due to forced normalization in scores, both sections are approximately normal. the mean score for verbal reasoning section was 462 with a standard deviation of 119, and the mean score for the quantitative reasoning was 584 with a standard deviation of 151.

Answer 1

main answer : the normal distribution of given graduate record  exam is 1,A(1)=0.3413

supporting answer:Because of its flared shape, a graphical representation of a normal distribution is sometimes referred to as a bell curve. The precise shape varies depending on the population distribution, but the peak is always in the middle and the curve is always symmetrical. The mean, mode, and median of a normal distribution are all the same.

body of the answer: given that x₁=mean+standard deviation

                                     given mean₁=462

                                                standard deviation =119

  x₁=462+119=581

  z₁=581-462/119=1

  A(1)=0.3413

given mean₂=584

        standard deviation=151

x₂=584+151

   =735

z₂=735-584/151

  =1

A(1)=0.3413

final answer:there fore both scores are normal
