Refer to the dataset “gapminder” from package “gapminder”. The questions for this project are:
Summarize and plot the median life expectancy (MLE) in 1952 for each of the 5 countries with the top MLE’s and for each of the 5 countries with the bottom MLE’s.
Summarize and plot the median life expectancy (MLE) in 2007 for each of the 5 countries with the top MLE’s and for each of the 5 countries with the bottom MLE’s.
Summarize and plot the median life expectancy in each year for the largest 5 countries in terms of 2007 population.
Summarize and plot the median life expectancy in each year for each continent.
In 1952, Europe, with 5 countries, Africa, with 4 countries, and Asia, with 1 country, were the continents with the highest Median Life Expectancy, specifically all three were over 60 years.
