Given the following summary statistics, calculate a point estimate for the slope of the least squares line,b₁

s_y=20 and s_x=10 and R=-0.75 and x-bar=120 and y-bar=90

Using the same set of summary statistics, as well as your point estimate of slope from the previous question, calculate a point estimate for the intercept,b₀.

Using the same set of summary statistics, calculate an R²for the least squares linear regression.
