What is the estimated regression slope coefficient round to


The data shown below indicate the average tuition (in dollars) over a six-year period for private and public colleges in a region. Complete parts a through c below. Use α= 0.01 where needed.

Year 1 2 3 4 5 6

Private 8,195.  9,587 11,774 12,364 12,364 16,080

Public 2,045 2,347 3,179 3,650 4,669 5,660

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 α=0.01
