Hi Dear ,I have given my 100% to solve your problem ,
So,please help me out by just thumbs up .
Thank you ,so much.

An alternate expression for the slope coefficient of the simple linear regression model is B1= r(Sy/Sx) where r is the Pearson correlation coefficient given by r= Sxy/ (√(SxxSyy) and Sy and Sx are the sample standard deviations of y and x, respectively. Use the data to show that this alternate formulation gives a slope coefficient that is numerically equivalent to what you found using the Least-squares estimations demonstrating that r(Sy/Sx) = Sxy/Sxx. Using the information given, find B0 and B1...

we have a bivariate data set and compute the following: r=.7, sy=9, sx=5, x-bar=13.5, y=51.6. We want to know the equation of the least-squares regression line, but we don't have a calculator. Determine the equation of the least-squares regression line from the given data. a. y=46.34+.39x b. y=-51.52+1.26x c. y=34.59+1.26x d. y=-6.624+.39x e. you can't compute the regression line without knowing the original data.
