A quality engineer for a camera manufacturer wants to shorten the flash recovery time. Flash recovery time is the least amount of time that is required between flashes. The engineer wants to determine whether a relationship exists between the voltage that remains in the camera battery immediately after a flash and the flash recovery time. The engineer also wants to determine whether there are differences in flash recovery time between old and new formulations of the battery. The engineer collects random samples of batteries made with the old and new formulations. The engineer measures the volts remaining immediately after a flash and the flash recovery time for each.
You can use this data to demonstrate Scatterplot, Marginal Plot, and other analyses that explore the relationship between two measurement variables.
|Flash Recovery||The time required for the camera to flash again|
|Volts After||The voltage remaining in the camera battery immediately after a flash|
|Formulation||The design of the battery: Old or New|
