Question: A regression methods was used to analyze the data from a study investigating the relationship between roadway surface temperature (x) and pavement deflection (y). Summary

A regression methods was 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 and

x y

mean 74.4 .17

Standard deviation 41.4 .66

Correlation between y and x .897

calculate the least squares estimates of the slope and intercept

I'm not sure of the steps to take to solve.
