For the past decade, rubber powder has been used in asphak cement to improve performance. An article codes are only and strength (3) nove Mrength (MPa) based on the following sample date: 112.3 97.0 92.7 16.0 1020 99.2 95.8 103.5 69.0 66.7 74.5 71.0 57.7 46.7 740 731 679 59.2 57.7 485 USE SALT () Obtain the equation of the least squares line. (Round all numerical values to four decimal places) y- Interpret the slope. O A one MPa Increase in axial strength is associated with an increase in the predicted cube strength equal to the ope. O A one MPa decrease in cube strength is associated with an increase in the predicted axial strength equal to the slope. O A one MPa decrease in axial strength is associated with an increase in the predicted cube strength equal to the slope. O A one MPa Increase in cube strength is associated with an increase in the predicted axdal strength equal to the slope. (b) Calculateſ 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 cannot be worted to its relationship with cube strength. The coefficient of determination is the number of the observed samples of axial strength of asphalt that cannot be explained by variation in cube strength The coefficient or determination is the number of the observed samples of axial strength of asphalt that can be explained by variation in cube strength 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 inner relationship with cube strength. Taking (c) Calculate an estimate of the error standard deviation in the simple linear regression model (Round your answer to three decimal places.) MPa
