 Find Regression line xbar=39.5,ybar=47.5,SDx=10.8,SDy=15,r=0.42 [ Calculator, Method and examples ]Solution:Your problem -> Regression line xbar=39.5,ybar=47.5,SDx=10.8,SDy=15,r=0.42byx = r * (sigma y)/(sigma x)byx = 0.42 * 15/10.8byx = 0.5833Regression Line y on xy - bar y = byx (x - bar x)y - 47.5 = 0.5833 (x - 39.5)y - 47.5 = 0.5833 x - 23.0417y = 0.5833 x - 23.0417 + 47.5y = 0.5833 x + 24.4583
