14. In a chapter Preview we presented a study showing that handling money reduces the perception pain (Zhou, Vohs &Baumeister, 2009). In the experiment a group of college students was told that they were participating in a manual dexterity study. Half of the students were given a stack of money to count and the other half got a stack of blank paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122° F) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study. | Counting paper Counting Money 7 8. 11 10 13 10 8. 11 5 7 15 12 14 10 (a) Is there a significant difference in reported pain between the two conditions? Use a two-tailed test moone with a = 0.01. (b) Compute Cohen's d to estimate the size of the treatment effect.
