Extracted text: What is the mean pavement deflection when the surface temperature is 95 °F? Round your answer to 4 decimal places (e.g. 98.7654). What change in mean pavement deflection would be expected for a 1 °F change in surface temperature? Round your answer to 5 decimal places (e.g. 98.76543).


Extracted text: 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, Σν 12.75, Σν 8.86, Σχ 1478, Ex? = 143215.8 and Ex;y; = 1083.67. Statistical Tables and Charts Calculate the least squares estimates of the slope and intercept. Estimate oʻ. Round your answers to 5 decimal places (e.g. 98.76543). Use the equation of the fitted line to predict what pavement deflection would be observed when the surface temperature is 85 °F. Round your answer to 4 decimal places (e.g. 98.7654). i 2.
