The data shown below indicate the average tuition (dollars) over a six-year period for private and public colleges in a region. Conduct a simple linear regression analysis of these data to predict the average tuition for private colleges based on the average public college tuition. Test the significance of the model using α = 0.01. What is the estimated regression slope coefficient? (Round to two decimal places as needed.) What is the estimated regression intercept? (Round to the nearest whole number as needed.) To test the significance, first determine the hypotheses to test. Choose the correct answer below: Ho: β1 = 0 HA: β1 ≠ 0 Ho: β1 ≤ 0 HA: β1 > 0 Ho: β1 ≥ 0 HA: β1 < 0 Ho: β1 < 0 HA: β1 ≥ 0 Determine the rejection region for the test statistic for α = 0.01. Select the correct choice below and fill in any answer boxes to complete your choice. (Round to two decimal places as needed.) Calculate the simple linear regression test statistic. (Round to two decimal places as needed.) Since the test statistic falls within the rejection region, conclude whether the regression model is significant. This indicates whether knowing the average public college tuition is useful in predicting the average private college tuition.
