Imperfect multicollinearity will...? O Not bias our estimates, but it will lower their precision by causing larger standard errors. O Bias our estimates, and it will increase the precision of our estimates because of smaller independent variance in the regressor O Bias our estimates, and it will lower their precision by causing larger standard errors. Not bias our estimates, and it will increase the precision of our estimates because of smaller independent variance in the regressor.
In order to test multiple hypotheses at once, we need to use...? O AX^2 test O A T-test O An F-test O An independence test
True or false: an F-test that indicates joint significance among several variables implies that all included variables are equally important to the joint significance? True, all included variables are equally important to the joint significance. O False, we don't know which of the variables contribute most to the joint significance.
Given the following equation: Wage = 5 + 1.5exper-0.15exper2 What is the marginal effect of experience on wage? Hint: take the partial derivative with respect to experience. O 8(wage)/(experience) =-0.15exper O 8(wage)/d(experience) =-0.30exper O 8(wage)/(experience) = 1.5-0.30exper O 8(wage)/(experience) = 1.5-0.15exper
