The data shown below indicate the average tuition (in dollars) over six-year period for private and public colleges in a region. Complete parts a through c below.

a. Conduct a simple linear regression analysis of these data in which the average tuition for private colleges is predicted by the average public college tuition. Test the significance of the model using ? =0.10

What is the estimated regression slope coefficient?

What is the estimate regression intercept?

b. To test the significance, first determine the hypotheses to test, Choose the correct answer below.

c. Determine the rejection region for the test statistics t for ? = 0.10. Select the correct choice below and fill in any answer boxes to complete your choice

Calculate the simple linear regression test statistics t.
