Which one(s) are true? I. Combination of high adjusted R2 and no statistically significant variables is an indication of multicollinearity II. Multicollinearity exists only in some regression models. III. With multicollinearity, it is possible for an F-test of overall significance to reject the null even though none of the individual t-tests do.
