Suppose that the true relationship between y; and ; is as follows, Yi = B₁ + B₂xi + Ui The error term satisfies that E[u₂] = 0 and Var(u) = 1. You find another variable zi whose sample correlation with x is equal to -1. Select correct statement(s). Because the correlation is equal to -1, we have %₁ = -₂. O If we add z; in the regression model along with ;, R² will be increased. Adding z; along with in the regression model is not plausible because of the perfect multicollinearity. O If we estimate the model y₁ = a₁ + a2%; + e₁, the estimator of a2 will be equal to -3₂, where B₂ is the OLS estimator of 32

A scatterplot showing the data is given below: Peak Current in Eleven Buffers with Added Nickel Solutio 60 120 140 100 Amount of nickel (pp million) Suppose a regression line was added to the plot above. If an additional measurement had been taken with the nickel of 62 parts per 10 and a peak current of 0.38 microamps, adding this observation would: O A. increase the intercept, decrease the slope. OB. increase the intercept, increase the slope. C. decrease the intercept, increase the slope. OD. decrease the intercept, decrease the slope. E. not affect the regression line.
