Lubov Fominskaja [6]

Answer:

z score for Maria is higher than Stephanie

Step-by-step explanation:

for Stephanie

GPA = 3.85

Mean of her school GPA = 3.1

Standard deviation = 0.4

$Z =\frac{x -\mu}{\sigma}$

$= \frac{3.85 -3.1}{0.4}$

Z =1.875

for Maria

GPA = 3.80

Mean of her school GPA = 3.05

Standard deviation = 0.2

$Z =\frac{x -\mu}{\sigma}$

$= \frac{3.80 -3.05}{0.2}$

Z =3.750

therefore z score for Maria is higher than Stephanie
