Question 3 1 pts Load the Assignment 2 dataset as2_sleep.csv in R. Consider a polynomial regression where the dependent variable is log(1+totwrk) (exactly as in Question 1), and the independent variables are age, age^2, age 3, and age 4 (e.g., a quartic regression model in age). Estimate the model in a way that ensures your standard errors are robust to heteroskedasticity. Which econometric problem best describes the large standard errors you obtain from this regression? O Omitted Variable Bias Heteroskedasticity O Imperfect Multicollinearity Too small a sample because N
