Transcribed Image Text:For the past decade, rubber powder has been used in asphalt cement to improve performance. An article includes a regression of y = axial strength (MPa) on x cube strength (MPa)
based on the following sample data:
112.3 97.0 92.7 86.0 102.0 99.2 95.8 103.5 89.0 86.7
74.7 70.7 58.0 49.2 74.3 73.0 68.3 59.5 57.3 48.9
(a) Obtain the equation of the least squares line. (Round all numerical values to four decimal places.)
%3D
Interpret the slope.
A one MPa decrease in axial strength is associated with an increase in the predicted cube strength equal to the slope.
A one MPa decrease in cube strength is associated with an increase in the predicted axial strength equal to the slope.
A one MPa increase in axial strength is associated with an increase in the predicted cube strength equal to the slope.
A one MPa increase in cube strength is associated with an increase in the predicted axial strength equal to the slope.
(b) Calculate the coefficient of determination. (Round your answer to four decimal places.)
Interpret the coefficient of determination.
The coefficient of determination is the proportion of the observed variation in axial strength of asphalt samples of this type that can be attributed to its linear relationship
with cube strength.
