Rico and Patrick love to go shark fishing. They wondered if a new brand of shark bait would help them catch more sharks. To test their idea, they bought a big container of bait for their next 3 trips to their top-secret fishing spot. Rico fished without any bait, while Patrick used the new bait. Both of them kept track of how many sharks they caught in 30 minutes, which is shown in the chart.
