To validate this claim, you create a random sample of 20 students during graduation and ask each student to anonymously report the amount of their student loan debt. Complete parts a through c. Check the numbers box below a. Construct a 90% confidence interval with these data to estimate the average student loan debt of students graduating at your school. The 90% confidence interval is from----- to------. (Round to two decimal places as needed. Use ascending order.) b) Do these results validate the claim of your school? c) What is the margin of error for this sample? $0 $0 $5 $100 $1,100 $0 $1,700 $2,450 $2,800 $1,900 $0 $2,100 $2,300 $2,900 $2,900 $0 $2,000 $250 $2,350 $2,750
