Please answer Question One based on the data provided, using R programming language.

Leader Assassination as a Natural Experiment One longstanding debate in the study of international relations concerns the question of whether individual political leaders can make a difference. Some argue that leaders with different ideologies and personalities can significantly affect the course of a nation. Others argue that political leaders are severely constrained by historical and institutional forces. Did individuals like Hitler, Mao, Roosevelt, and Churchill make a big difference? The difficulty of empirically testing these arguments stems from the fact that changes in leadership are not generally random. In this exercise, we consider a natural experiment in which the success or failure of assassination attempts may be essentially random, at least with respect to the outcomes in which we are interested. This exercise is based on: Jones, Benjamin F, and Benjamin A Olken. 2009. "Hit or Miss? The Effect of Assassinations on Institutions and War." American Economic Journal: Macroeconomics 1(2): 55-87. Each observation of the CSV dataset leaders.csv contains information about an assassination attempt. The variables are: The polity variables represent "Polity scores" from the Polity Project. The Polity Project assigns an annual Polity score to all countries in the world from 1800 to the present as a measure of each country's political institutions. The Polity score is a 21-point scale ranging from -10 (hereditary monarchy) to 10 (consolidated democracy). The result variable is a 10 category text variable describing the result of each assassination attempt: dies between a day and a week; dies between a week and a month; dies within a day after the attack; dies, timing unknown; hospitalization but no permanent disability; not wounded; plot stopped; survives but wounded severely; survives, whether wounded unknown; wounded lightly. Question 1 (all questions 10 pts each) How many assassination attempts are recorded in the data? What is the average age of a leader across all assassination attempts in the data? What is the first year in which an assassination attempt is recorded in the data? Answer 1 \# insert code here Insert written answer here
