A researcher asked participants to watch a short romantic movie clip. The movie clip depicted a romantic scene ending with two long-lost lovers embracing in a kiss. After the short romantic movie clip, participants were asked to indicate how the romantic movie clip affected their mood on a bipolar scale ranging from -3 (much worse mood) to +3 (much better mood), with o indicating no change in mood. The results are given below. It was assumed that the average participant would give a rating of 0 if there were no change in mood. Test whether or not participants reported a significant change in mood at a .05 level of significance
