Problem 7E
Applet Exercise Move down to the portion of the applet labeled “Curvilinear Relationship” associated with the applet Fitting a Line Using Least Squares.
a Does it seem like a straight line will provide a good fit to the data in the graph? Does it seem that there is likely to be some functional relationship between E(Y ) and x?
b Is there any straight line that fits the data better than the one with 0 slope?
c If you fit a line to a data set and obtain that the best fitting line has 0 slope, does that mean that there is no functional relationship between E(Y ) and the independent variable? Why?
