1. Nationwide, the average total amount of student loan debt in 2012 is normallydistributed with a μ = $29,400. Assume that a sample of 36 students is randomlyselected from a public university. Their student loans have X = $27,400 and s = $9,000. Conduct a proper statistical procedure to test whether the average student loan in this public university is different from $29,400, usingα = .10.
