Challenge #24: ARIMA Time Series

[barrymoe]

Spent some time initially trying to figure out how to use the multi-row tool to substitute the averages for the null data, but ended up going with the double summarize method. Also a good reminder and learning experience on ARIMA and how to read the outputs.
