Use the data in COUNTYMURDERS to answer this questions. Use only the data for 1996.
(i) How many counties had zero murders in 1996? How many counties
had at least one execution?
What is the largest number of executions?
(ii) Estimate the equation
murders = b0 + b1execs + u
by OLS and report the results in the usual way, including sample size and R-squared.
(iii) Interpret the slope coefficient reported in part. Does the estimated equation suggest a deter-
rent effect of capital punishment?
(iv) What is the smallest number of murders that can be predicted by the equation? What is the
residual for a county with zero executions and zero murders?
(v) Explain why a simple regression analysis is not well suited for determining whether capital pun-
ishment has a deterrent effect on murders.

1. In the simple regression model y = + β1x + u, suppose that E (u) 0. Letting oo-E(u), show that the model can always be rewrit ten with the same slope, but a new intercept and error, where the new error has a zero expected value 2. The data set BWGHT contains data on births to women in the United States. Two variables of interest are the dependent variable, nfan birth weight in ounces (bught), and an explanatory variable,...
2. Use the data in hpricel.wfl uploaded on Moodle for this exercise. We assume that all assump- tions of the Classical Linear Model are satisfied for the model used in this question. (a) Estimate the model and report the results in the usual form, including the standard error of the regression. Obtain the predicted price when we plug in lotsize - 10, 000, sqrft - 2,300, and bdrms- 4; round this price to the nearest dollar. (b) Run a regression...
causally! What might be going on C12 Use the data in ECONMATH to answer the following questions. 0 Estimate a model explaining colgpa to hsgpa, actmth, and acteng. Report the results in the usua form. Are all explanatory variables statistically significant? (ii) Consider an increase in hsgpa of one standard deviation, about .343. By how much does colgpo increase, holding actmth and acteng fixed. About how many standard deviations would the actmth have to increase to change colgpa by the...
