Compute the least-squares regression line for predicting y from x given the following summary statistics. Round the slope and y-intercept to at least four decimal places. x = 8.1 sx = 1.3 y = 41,000 sy = 1.9 r = 0.40
Added by Elijah H.
Step 1
The formula for the slope is: b1 = r * (sy / sx) Substituting the given values: b1 = 0.40 * (1.9 / 1.3) = 0.5846 Show more…
