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.
