The top row shows hours of sleep for a given employee and the bottom row shows the next day"s relative test performance. slee p scor e. R^2=0. 89742 (c) (6 pts) now use the excel trendline method to estimate a regression equation of the form y = a + bx + cx2. Report the estimated equation and the r 2. Cut and paste the diagram into the space below.
