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

Answer:
Step-by-step explanation:
X X X X . X X X
^ this is the hundreds place
X X X X . X X X
^ this is the hundredths place
a) 300 Because the place behind it is less than 5.
b) 1300 The place in the tens is 5 or greater.
c) 10,000 The place in the tens is 5 or greater which causes the 9 in the hundreds to go up which also causes the 9 in the thousands to go up as well.
d) 1,100
e) 700
a. difference in wages = 941 - 770 = $171
