Question
Regression methods were used to analyze the data from a study
investigating the relationship between roadway surface temperature
(x) and pavement deflection (y).
Summary quantities were n = 20, Ey; = 12.75, Ey = 8.86,
Σχ1478 , Σ;143215.8 and Σx:y- 1083.67.
Suppose that the observed value of pavement deflection at x = 90 is y
= 0.753. Use the simple linear regression model you obtained to
calculate the value of the corresponding residual. Round your answer
to three decimal places as needed.
