Answer:
 the probability that the mean student loan debt for these people is between $31000 and $33000 is 0.1331
Step-by-step explanation:
Given that:
Mean = 30000
Standard deviation = 9000
sample size = 100
The probability that the mean student loan debt for these people is between $31000 and $33000 can be computed as:





From Z tables:


Therefore; the probability that the mean student loan debt for these people is between $31000 and $33000 is 0.1331

The domain is about how far left-to-right the graph goes. 
In relation to the x-axis, the graph starts at x = –3 (with an open circle at –3) and then continues over to the right forever. 
This is the shown in the picture with the red markup.
In interval notation, this is (-3, infinity).
Remember to use that left-to-right orientation for interval notation!
The range is in turn about how low to how high the graph goes. 
On the graph, I’d do the same thing I did on the red marked up graph and compare the graph to the y-axis.
The graph starts down at y = –5 (with an open circle at –5) and then continues on up forever. 
In interval notation, this is (-5, infinity).
