Question

4) For the dataset below, perform a regression and find the best-fit equation and coefficient of determination. Then state how well the regression line fits the dataset. Use the shortcut (or computing) formulas. Make sure you show all necessary work. X\Y\10\75\14\65\20\59\26\44\30\32\X$^2$\Y$^2$\XY Based on the fit of the line to the dataset according to the R$^2$ value, how appropriate was it to assume a linear equation could be fit to the data? (Very, somewhat, not very) Should you use this equation to make predictions? If so, find the predicted y-value for an x-value of 17 and for an x-value of 32. Which prediction is interpolation? Which is extrapolation? Which is more reliable and why?
