Anomaly detection with Z-scores

As a trading analyst, we're seeking to identify anomalous price points for trading opportunities. The higher the number of anomalous price points, the more opportunity (pricing arbitrage) potentially exists.

In our case, we've ascertained that any value with a Z-score greater than +3 is an anomalous price point that warrants further analysis, as this represents an opportunity for us to sell water at a premium price. Let's see how many opportunities we can identify!
