Zhou and Vohs (2009) published a study showing that handling money reduces the perception pain. 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 pieces of paper. After the counting task, the participants were asked to dip their hands into bowls of very hot water (122 degrees) and rate how uncomfortable it was. The following data show ratings of pain similar to the results obtained in the study. Is there a significant difference in reported pain between the two conditions? Use a two-tailed test with alpha= .05 Counting Money Counting Paper 7 9 8 11 10 13 6 10 8 11 5 9 7 15 12 14 5 10 1.State the hypothesis a.H0: b.H1: 2.

1.State the hypothesis
a.H0:
b.H1:
2. Locate the critical region
a.df =
b.The critical value of t =
3.Compute the statistic
a.Pooled variance (s2p) =
b.standard error (sM-M) =
c.t =
d. Cohen's d =
e.r2=
f. Confidence Interval:
4. Make the decision.
a. Did you reject or retain the null?
b. Is there a significant effect?
c. State the findings in APA style. For example, the results indicate that the IV has a significant effect on the DV, t (df) = #, p < .05, d = #.
