Question 14 3 pts Suppose that you estimate a multiple regression model, but that you inadvertently omit an explanatory variable that is correlated with the dependent variable. In this case, the coefficients on the included variables will always be biased. the coefficients on the included variables will always be unbiased, but the standard errors and test statistics will be biased. there is no effect on the coefficients of the included variables since the omitted variable has been omitted. the coefficients...

Question 4 3 pts Consider the estimated multiple regression model using OLS, with the standard errors in parentheses below each estimated coefficient. There are 1,576 observations in the sample: Y = 10 + 2X2i - 5Xzi (3) (1.5) (2) Suppose that the sample mean of Y is 30. For the 18th observation (i=18) in the sample, the value of X2 is 50, the value of X3 is 16, and the value of Y is 20. The residual associated with the...

Question 3 3 pts Suppose that you estimate a regression model with a sample size of 112 observations and 10 explanatory variables, including the intercept, using ordinary least squares and the residual sum of squares from this estimated model is 22. You then conduct a Ramsey's RESET on this model and the residual sum of squares from the Ramsey regression is 20. The test statistic associated with this Ramsey's RESET is and you can conclude at the 5- percent level...
