You are provided with data for several nations from the Human Development Report, 2017.

1. Compute summary statistics (mean, median, mode, standard deviation etc.) for the variables of GDP (GDP per capita in thousands of dollars) and Internet use.

Provide descriptions of the distributions based on the summary statistics. Address skewness in your description.

2. Generate a scatterplot with clearly labeled axes CO2 and GDP. CO2 will be on the Y axis. Comment on what you see.
3. Compute the correlation between CO2 and GDP and interpret it. Refer to both the strength and direction of the correlation in your interpretation.
4. Using the variable Internet Use, construct the 1^st, 2^nd, and 3^rd standard deviation from the mean intervals and calculate the percentages for each. Then make a short interpretation on whether they match the percentages in the Empirical Rule.
