Find the equation for the least-squares regression line

 

xyxyxx1584025291090813111314312141719323289sum4250596516

 

We find for the values:

N=4X=42Y=50XY=596X2=516

 

Slope(b)=NXY(X)(Y)NX2(X)2=4596(42)(50)4516(42)2=2384210020641764=284300=0.94666666667

 

Intercept(a)=Yb(X)N=500.94666666667(42)4=500.94666666667(42)4=5039.764=10.244=2.56

 

Regression Equation(y)=a+bxy=2.56+0.94¯6x
