Answer:
17
Step-by-step explanation:
54 has 4 ones
and 5 tens
37 has 7 ones
and 3 tens
subtracting ones
7 ones are taken from 54
so along with the existing 4, 1 ten is decreased and another 3 ones are decreased resulting in 7 ones now
now 54 has 5-1= 4 tens
subtracting tens we get 4-3=1
Therefore 1 ten and 7 ones
⇒ 17

Data
mean (
): 80
standard deviation (
): 4
Normal distribution table is in figure attached
.
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
