E6-45B Create a scatter plot (Learning Objective 3)

Martha LaChance, owner of Posies Unlimited, operates a local chain of floral shops. Each shop has its own delivery van. Instead of charging a flat delivery fee, LaChance wants to set the delivery fee based on the distance driven to deliver the flowers. LaChance 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............................... 15,500 $5,400 February............................. 17,500 $5,350 March................................. 14,400 $4,980 April.................................... 16,400 $5,280 May..................................... 16,900 $5,580 June.................................... 15,300 $5,010 July..................................... 13,500 $4,590 Requirements 1. Prepare a scatter plot of Posies Unlimited’s volume (miles driven) and van operating costs.
2. Do the data appear to contain any outliers? Explain.
3. How strong of a relationship is there between miles driven and van operating expenses?
