Do you turn off the light when you leave the room? South Korean researchers wondered how they could increase the number of people who do (Ahn et al., 2014). They compared two poster campaigns. In one, an image of a light bulb was anthropomorphized by giving it eyes, nose, and a mouth, as well as adding the words, "I'm burning hot, turn me off when you leave!" (p. 225). In a second, there were no human features on the light bulb and the text simply said, "Our bulbs are burning hot, turn the lights off when you leave!" (p. 226). Participants were randomly assigned to view one of these posters and then were asked to rate a series of items about how likely they would be to behave in an environmentally friendly manner. The scale went from 1 (very unlikely) to 9 (very likely). The summary statistics for the data belowapproximate the actual means and standard errors in the study.

1. Conduct all six steps of an independent-samplesttest. Be sure to label all six steps.
2. Report the statistics as you would in a journal article.
