hypothesis you have tested, and what your conclusion is. j. Can you use regressions (3) and (4) to test the same hypothesis as in (i), this time using the R? formula for the homoskedasticity-only F-statistic? Explain. (For this question, assume homoskedasticity, so that the use of the homoskedasticity-only F-statistic is justified if one can use it in this situation.) k. Using regression (4), estimate the effect on Infimpop of changing from lackof = 7 (extremely limited political freedoms) to lackof = 5 (some political freedoms), holding constant the values of the other regressors in regression (4). I. Using regression (5), explain in words what the coefficient on the interaction term higdpec * lackpf means. m. Using the results in Table 1, write a brief paragraph summarizing your findings about the relation between terrorist fatalities and economic conditions, political freedoms, and ethnic and religious diversity. Your discussion should be based on your results (that is, on the empirical evidence, not your opinions); however you do not need to refer to specific regressions.
