Compute the US rate by using summarize to sum over states. Call the variable rate.
- The US rate for each disease will be the total number of cases divided by the total population.
- Remember to convert to cases per 10,000.
You will need to filter for !is.na(population) to get all the data.
Plot each disease in a different color.
