Smokers by age

In this exercise, your task is to compare the demographics of policyholders based on their age and smoker status. To achieve this, you will generate two histograms representing the ages of smokers and non-smokers. The histograms will be displayed one on top of the other by manipulating the figure layout.

The DataFrames and StatsPlots packages have been imported, and the insurance DataFrame, containing the relevant data, has been loaded for your convenience.
