Question

To test the effect of visual distraction on reaction time, a researcher tests a group of 13 subjects under two conditions. In the control condition, the subjects have to press a key as soon as possible when a target stimulus appears on a blank computer screen. In the experimental condition, the subjects are given the same task, but the target stimulus always appears surrounded by other distractor stimuli. Reaction time is measured in milliseconds in both conditions. The data are below. Test whether distracters affected reaction time using a t-test.
