1. Explore the Egyptian exports series. Is data stationary? What ARIMA model should be used?

    egypt <-global_economy |>
      filter(Code == "EGY")
  2. Repeat the process for the Central African Republic CAF exports.

    egypt <-global_economy |>
      filter(Code == "EGY")
  3. Run through the code for the rest of the examples. Explore and understand what the code is doing.
