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.
