Step-by-step explanation:

Data

mean ( $\mu$ ): 80

standard deviation ( $\sigma$ ): 4

Normal distribution table is in figure attached .

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

Z = (85 - 80)/4 = 1.25

Area below curve = 0.3944

Z = (82 - 80)/4 = 0.5

Area below curve = 0.0199

Proportion of exam scores between 82 and 85?

0.3944 - 0.0199 = 0.3745
