(a)
Determine the least squares regression line.
(Be sure to save your unrounded values of b0
and b1 for use in Problem #6 below.)
(b)
Draw the least squares regression line accurately on a
scatterplot. Then look to see which (x, y) pairs
are above the regression line. Then add up the
y-values for all of the (x, y)...
