A researcher wishes to test the claim that the average cost of tuition and fees at a four-year public college is greater than $5,700. She selects a random sample of 36 four-year public colleges and finds the mean to be $5,950. The population standard deviation is $659. Is there evidence to support the claim at the α = .05 level?
