Question

Will someone please help me with these questions.

The table shows the average annual cost of tuition at 4-year institutions from 2003 to 2010.  
 1.) Find the least squares regression equation using the school year (in number of years after 2000) for the input variable and the average cost (in thousands of dollars) for the output variable.

2.)What is the best estimate for the average cost of tuition at a 4-year institution starting in 2000. (Hint: look at the y-intercept)

3.)What is the best estimate for the average cost of tuition at a 4-year institution starting in 2020.

4.)What does the slope mean in context of the situation?

5.)Most students are not able to afford this tuition for 4 years. What are some ways that you can lower the cost of your college tuition? If you don’t plan to attend college, what things can do you post- HS graduation to continue your education or provide for yourself financially?
