Question

The average student loan debt for college graduates is $25,350.
Suppose that that distribution is normal and that the standard
deviation is $14,450. Let X = the student loan debt of a randomly
selected college graduate. Round all probabilities to 4 decimal
places and all dollar answers to the nearest dollar.

a. What is the distribution of X? X ~ N(,)

b Find the probability that the college graduate has between
$12,500 and $26,700 in student loan debt.

c. The middle 20% of college graduates' loan debt lies between what
two numbers?

Low: $

High: $

I know how to figure out A and B. I am getting stuck on C. Try to explain in as many steps as possible or how to do it on a calculator. My teacher allows us to use a calculator but I can't figure out how to do Problem C on there. Thanks

Average student loan debt is $25850, with normal
distribution and std deviation is $10,700. The middle 20%of loan
debt lies between what two numbers?

The average student loan debt for 2016 college graduates who
borrowed to get through school was $37,172. Is this still true
today? You get a random sample of 150 recent college graduates and
find that their mean student loan is $36,654 with a standard
deviation of $4,000. Test the claim at the 5% significance level
using PHANTOMS.
