Consider the regression model y = Bo + B1x1 + B2x2 + B3(x1 × x2) + u. Which of the following statements is false? Select one: O a. \(\beta_3 \) indicates the effect of a unit increase in \( \sqrt{x_1 x_2} \) on the conditional mean of \( y \). O b. The interaction term allows the effect on the conditional means of \( y \) of a change in \( x_1 \) to depend on the value of \( x_2 \). O c. \(\beta_1 \) indicates the effect of a unit increase in \(x_1\) on the conditional mean of \( y \) if \( x_2 \) is equal to zero. O d. \(\beta_3 \) cannot normally be interpreted on its own in a meaningful way. O e. The interaction term allows the effect on the conditional means of \( y \) of a change in \(x_2 \) to depend on the value of \( X_1 \).
