I loved getting to use new tools. I got slightly different answers to others but we all have the same method so I think it's ok.

First time with ARIMA! A use-case is coming up, so I learned a lot from this tool. Though it's kinda hard to play around with lol.

First time using time series tools. Would be interested to further explore this.

P.S. might make more sense to train / test the model on a training set before making predictions. But would need more data as holding any out would mean some weeks do not have 2 data points.

I thought I had done this correctly, but my answers were just slightly off.  So I looked at the solution.  My workflow output Matched the solution! Maybe to model changed? Anyway, if you're attempting this one - compare to the solution for your numbers.
