1} Create a new binary.T variable higdppc, which equals one if gdppc is greaterthan or equal to the median in the data set, and which equals zero otherwise; also create the interaction variables hijack = higdppcxiockpf and hijack? = higdppcwiociqaf. Estimate the regressions in Table l and ll in the empty entries. You rnaj,r write in the entries by hand or type them using the .doc electronic version of the table on the course web site. Note: for all calculations, only use the countries that have nonzero values of mpop and nonmissing values of gdppc. 2} Regression {'6} produces two regression lines, one for higdppc = i] and one for higdppc = 1. Produce a scatterplot of inftmpop vs. locirpf, showing the two regression lines. This can he done either by producing two scatterplots, one for higdppc = I] and one for higdppc = l, or by combining the two scatterplots into a single graph. Use regression (E) to write out the estimated regression Lines for the two groups {in slope-intercept form)
