True [87]

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
