Soccer players and former teammates Romelu Lukaku and Zlatan Ibrahimović got into an altercation. Ibrahimović implied that he was a better striker than Lukaku. Looking at their careers in clubs and in their respective national teams, Ibrahimović scored 467 goals in 750 games, and Lukaku scored 266 goals in 517 games. Neither of their careers are over, so this is just a sample of what both players can do. At the 1% significance level, can we claim that Ibrahimović has a bigger proportion of goals per game than Lukaku? To answer this question, perform a two-proportions z-Interval test. Do not forget to define your hypothesis and interpret your results!
