Fleetwood family enjoys the family picnics on weekends. They are mainly concerned with the time it takes to ignite the coal in the barbecue and their son who is an industrial engineer has recorded the brand and the quality rating of the coal in respect to the time it takes for it to be ignited fort he 2011 picnics they have done. His analysis results are given below.
