Question: In an experiment designed to study the effects of illumination level on task performance, subjects were required to insert a fine-tipped probe into the eyeholes of ten needles in rapid succession both for a low light level with a black background & again at a higher light level with a white background. Each data value is the time [in seconds] to complete the task.
