What to do

The tasks below are described in a way that assumes that everything is in units of MONTHS (rate parameters, therefore, have units of inverse days). If any quantity is not given in those units, you need to convert it first (e.g. if it says a week, you need to convert it to 7 days).

Task 1:

Task 2:

Note: The ‘pathogen in the environment’ units are arbitrary here, and parameters are chosen such that everything fits (mostly) into a single plot. To compare with real data, where environmental pathogen load might be very high, you would need to show separate plots or plot on a log scale.
