Question 1192825
Here, you mean a sample of 1, or probability of selecting a person/insurance..., because there is no other sample size given

=(x-mean)/sigma
>(120000-115000)/37000=5/37=0.14
probability is 0.4443
-
this is z>-9/37=-9.24
probability is 0.5948
-
If you subtract the first from the second, you arrive at the 106-120 interval and that has probability of 0.1505. If you use a calculator and use the fraction, you will get a more exact result, but those aren't the directions.
