I began studying regression analysis today: A problem in my textbook asks me to find the estimated regression function for the following data.

enter image description here

For the previous problems, I've just used the formulas involving $\overline{X}$ and $\overline{Y}$. How can I do this one since the data isn't given completely?

You can only form an estimate based on the data you have. Ignore the fact that there are $39$ data points you don't know and estimate based on the ones you do, using the same technique you have used before. For comparison, I find $f(x)=11.04545+17.86363x$ from a spreadsheet

  • That's what I did, but the solutions manual has something different. Maybe the solution is the actual function with the missing 39 data points, but they don't indicate that at all. – mXdX Jul 31 '19 at 03:56
