Answer:
60.06%
Explanation:
For each of the amounts first of all we get the z values.
For $32,000 z= (Amount - Mean)/Standard deviation
z= (32,000- 40,000)/5,000= -1.6
For $42,000, z= (42,000- 40,000)/5,000
z= 0.4
Using probability tables to find the proportion of commission between 0.4 and -1.6, we will need to add 0.4452 and 0.1554.
This gives 0.6006= 60.06%
So the salesperson earns 60.06% commission between $32,000 and $42,000.
