Upcharging older smokers

In this exercise, your objective is to examine how age and smoker status influence the cost of insurance premium charges. To achieve this, you will create a scatter plot that showcases insurance charges against age, grouped by smoker status. The DataFrame recipe will be employed to facilitate this process.

You can leverage the pre-loaded insurance DataFrame, which contains the requisite data for the analysis. The DataFrames and StatsPlots packages have been imported.
