Reject Ho. The mean difference is significant.
O Fail to reject Ho. The mean difference is significant.
Now assume that the data are from a repeated-measures study using the same sample of n =9 participants in both treatment conditions. Compute
the variance for the sample of difference scores and the estimated standard error for the mean difference. (Hint: You should find that the repeated-
measures design substantially reduces the variance and the standard error.)

![Swearing is a common, almost reflexive, response to pain. Whether you knock your shin into the edge of a coffee table or smash your thumb with a
hammer, most of us respond with a streak of obscenities. One question, however, is whether swearing has any effect on the amount of pain that you
feel. To address this issue, Stephens, Atkins, and Kingston (2009) conducted an experiment comparing swearing with other responses to pain. In the
study, participants were asked to place one hand in icy cold water for as long as they could bear the pain. Half of the participants were told to repeat
their favorite swear word over and over for as long as their hands were in the water. The other half repeated a neutral word. The researchers recorded
how long each participant was able to tolerate the ice water. After a brief rest, the two groups switched words and repeated the ice water plunge.
Thus, all the participants experienced both conditions (swearing and neutral) with half swearing on their first plunge and half on their second. The
data in the following table are representative of the results obtained in the study and represent the reports of pain level of n = 9 participants.
Complete the following table and find M and SS for each group of scores and for the differences.
