A linear regression analysis was performed using as a predictor variable. The p-value associated with the regression coefficient for x₁ was 0.02, and the sign of the coefficient was negative. Another analysis was performed, this time using both x₁ and x₂ as predictor variables.

In the second analysis, the partial regression coefficient for x₁ had a positive sign and the p-value associated with it was 0.39. Given these results, would multicollinearity appear to be present?
