Use the following STATA output to test the one-sided alternative hypothesis that the true proportion of females who support stricter gun control laws is higher than the true proportion of males who support stricter gun control laws at the .05 level. prtest gun_control if regista=1, by (female) Two-sample test of proportions 0.

Make sure you compute and report both the observed test statistic and p-value (and what you are comparing these against)
