Nothing has changed. With a 5 .05, is there a significant difference between the two treatment conditions?

b. Now assume that the data are from a repeatedmeasures study using the same sample of n 5 9 participants in both treatment conditions. Compute the variance for the sample of difference scores, the estimated standard error for the mean difference and the repeated-measures t statistic. Using a 5 .05, is there a significant difference between the two sets of scores? (Because there no longer are consistent individual differences you should find that the repeated-measures t no longer reduces the variance.)
