Do the above data indicate a significant difference in pain tolerance between the two conditions? run a paired* t-test and show all the steps involved in hypothesis testing as shown in the sample solution. The steps include the following: Write the null and alternative hypotheses the output table showing the t and p-value State your conclusion about whether the numbers indicated a significant difference.
In an effort to demonstrate that swearing can help reduce ratings of pain, a researcher asked participants to plunge a hand in ice water as long as the pain would allow. In one condition, the participants were asked to repeat their favorite curse words while their hands were in water.I n the other condition, the participants repeated a set of neutral words .
