E6-26A Create a scatter plot (Learning Objective 3)

Kara Woo, owner of Flower Power, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, Woo wants to set the delivery fee based on the distance driven to deliver the flowers. Woo wants to separate the fixed and variable portions of her van operating costs so that she has a better idea how delivery distance affects these costs. She has the following data from the past seven months:

Month Miles Driven Van Operating Costs January...................................... 16,000 $5,490 February.................................... 17,500 $5,700 March........................................ 14,900 $4,910 April........................................... 16,200 $5,340 May............................................ 16,900 $5,820 June........................................... 15,100 $5,410 July............................................ 14,500 $4,920 Requirements 1. Prepare a scatter plot of Flower 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?
