You generate a scatter plot using Excel. You then have Excel plot the trend line and report the equation and the r2 value. The regression equation is reported as y=−99.94x+68.43 and the r2=0.2401. What is the correlation coefficient for this data set? r = This means to get the sqare root of 0.2401 right? so answer is 0.49? But I am
