For a repeated measures study comparing two treatments with a sample of n=16 participants, a researcher obtains a sample mean difference of MD = 3.3 with SS = 315 for the difference scores. Calculate the repeated-measures t statistic for these data using a two-tailed test, and determine if it is enough to reject the null hypothesis. For this test use a=.01.
