This project is about Health, here I explored four datasets from World Health Organization:

• Prevalence of obesity among adults, BMI >= 30 (%);
• Life expectancy (years);
• Countries that have passed legislation on Universal Health Coverage (UHC);
• Alcohol consumption in litres of pure alcohol.

There are 176 observations.

There are 3 hypothesis tests:

1. Countries with a Universal Health Coverage have a higher Life Expectancy? H0: Countries with UHC have a life expectancy <= mean(life expectancy) H1: Countries with UHC have a life expectancy > mean(life expectancy)

2. Countries that have a higher obesity among adults have a lower life expectancy? H0: Countries with higher obesity have a life expectancy >= mean(life expectancy) H1: Countries with higher obesity have a life expectancy < mean(life expectancy)

3. Countries that have higher alcohol consumption have a lower life expectancy? H0: Countries with higher alcohol consumption have a life expectancy >= mean(life expectancy) H1: Countries with higher alcohol consumption have a life expectancy < mean(life expectancy)

Hypothesis test: ttest_ind Significance level = 0.02
