Round your answers to three decimal places.
a. Compute R? .
0.932 O
b. Compute R .
0.898
c. Does the estimated regression equation explain a large amount of the variability in the data?
Yes
Explain. Hint: If R is greater than 70%, the model explains a large amount of variability.
Since the adjusted coefficient of determination is grester
than 70%, the model does
explain a large amount of variability.
