(2) A state executive claims that the average cost of tuition at public colleges is $5700. A researcher wishes to test the claim that this cost is greater than $5700. She selects a random sample of 36 public colleges and finds the mean to be $5950.The population standard deviation is $659. Is there enough evidence to support the claim that the cost of tuition is greater than $5700 at a 0.05?
