Please use the accompanying Excel data set oraccompanying Text file data set when completing thefollowing exercise.
The "cold start ignition time" of an automobile engine is beinginvestigated by a gasoline manufacturer. The following times (inseconds) were obtained for a test vehicle: 1.68, 1.85, 2.60,2.33, 3.01, 3.18, 2.44, 1.98.
A second formulation of the gasoline was tested in the samevehicle, with the following times (in seconds): 1.91, 2.01,3.19, 3.24, 2.55, 2.77, 3.44, 2.40, 1.97, and 3.27. Use this newdata along with the cold start times to construct comparative boxplots.
Choose the correct answer.
