Regression methods were used to analyze the data from a study investigating the relationship between roadway surface temperature (x) and pavement deflection (y). The simple linear regression model is y = 0.33 + 0.0042x. Bo + Bix. (a) Suppose that temperature is measured in °C rather than °F. Determine regression coefficients for the new model y Round your answer to two decimal places (e.g. 98.76). %3D i Round your answer to four decimal places (e.g. 98.7654). i %3D 5) What change in expected pavement deflection is associated with a 1°C change in surface temperature? ound your answer to four decimal places (e.g. 98.7654).
