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 $23,500. You take a random sample of 146 college students in the state of Vermont and find the mean debt is $24,500 with a standard deviation of $2,800. We want to construct a 90% confidence interval for the mean debt for all Vermont college students.
We have the following transformations: y = f (x + c): moves the graph c units to the left. y = 10 (x + 2) -10 y = 10x + 20-10 y = 10x + 10 y = f (x) - c: move the graph c units down. g (x) = 10x + 10 - 12 g (x) = 10x - 2 Answer: the function g (x) is given by: g (x) = 10x - 2
