Given the following summary statistics, find the slope and y-intercept for the regression equation.
Sample Standard Deviation: Sx 3.45
Sample Standard Deviation: Sy 1.89
Correlation: r -0.77
Sample Mean: x-bar 20.82
Sample Mean: y-bar 65.94
Round your answers to 2 decimal places. In calculating the y-intercept, use the value for the slope before it was rounded.
