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.

Student Debt – Vermont: The average student
loan debt of a U.S. college student at the end of 4 years of
college is estimated to be about $22,600. You take a random sample
of 136 college students in the state of Vermont and find the mean
debt is $23,500 with a standard deviation of $2,200. We want to
construct a 90% confidence interval for the mean debt for all
Vermont college students.
(a) What is the point estimate for the...
