Suppose that you estimate a regression model with a sample size of 92 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 of significance that _________________.
4; the regression is misspecified.
2; the regression is not misspecified.
5; the regression is misspecified.
1; the regression is not misspecified.

To help schedule staffing and equipment needs, a large hospital uses a multiple regression model to predict its bed census' y, the number of beds occupied at the end of each day. Using hospital records from the most recent 22 days, a total of 4 independent variables are used to find the estimated regression model. Let BB2.B, denote the coefficients of the 4 variables in this model. A computer printout indicates that the total sum of squares (SST) associated with...
