In which
z is the zscore that has a pvalue of .
For this problem, we have that:

Answer:
$68,213
Step-by-step explanation:
The median is the middle value number.
So you need median for Virginia.
First lets see how index and income are connected.
To do this divide the income by the index to see if you have a constant value you can use.
535.434783 = Arkansas
535.381944 = Alabama
535.58 = Arizona
535.669236 = Alaska
535 is constant in all of these.
Let's multiply the index by 535.
127.2*535 =68212.5
For median income, you need a whole number so lets round up.
68213
So Virginia would have a median income rate of $68,213
