Kim Reynolds, owner of FlowerPower, operates a local chain of floral shops. Each shop has its own delivery van.

She has the following data from the past seven months: (see picture)
Requirements
1. Prepare a scatter plot of Flower PowerFlower Power's volume (miles driven) and van operating costs.
2. Does the data appear to contain any outliers? Explain.
3. How strong of a relationship is there between miles driven and van operating costs?
