Assume you are an art therapist studying a technique (throwing paint at a canvas) you think will increase peoples' positive mood. You randomly select 10 of your clients and ask them to throw paint for a certain number of minutes (between 1 and 10 minutes). After throwing paint, you asked them to rate their mood on a scale ranging from 1 (extremely negative) to 10 (extremely positive). Here are their scores: Participant Time spent Positive mood # throwing paint rating 1 1 2 4 2 2 3 2 2 6 4 3 5 4 4 16 6 8 7 6 8 7 8 9 8 10 10 10 10 Is this a one-tailed or two-tailed test? one-tailed two-tailed No answer text provided.
