Consider the following values for the dependent and independent variables:
x y
6â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦.5
9â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦20
14â€¦â€¦â€¦â€¦â€¦â€¦â€¦..28
18â€¦â€¦â€¦â€¦â€¦â€¦â€¦..30
22â€¦â€¦â€¦â€¦â€¦â€¦â€¦..33
27â€¦â€¦â€¦â€¦â€¦â€¦â€¦..35
a. Develop a scatter plot of the data. Does the plot suggest a linear or nonlinear relationship between the dependent and independent variables?
b. Develop an estimated linear regression equation for the data. Is the relationship significant? Test at an Î± = 0.05 level.
c. Develop a regression equation of the form = b0 + b1 ln (x). Does this equation provide a better fit to the data than that found in part b? |
