A group times how long it takes two cans to roll down a ramp fifty times for each can. They then count up all their data and make a histogram
As part of their conclusion in their lab report, they write: “The max to min ranges for the times for each can are 2.8 to 3.6 seconds and 2.5 to 3.0 seconds. Since the ranges overlap, we must conclude that the cans are the same. However, the histogram seems to show two different peaks. We don’t know exactly what to make of that.” Write a response to this group, including:
• What you think their conclusion should be, and why
• What information the max to min range gives them
• A suggestion for another type of range besides max to min that they should think about using
