The question was: Can it be concluded that the treatment lowered pain?

Answer and explanation: The answer is "Yes." The treatment group rated their pain significantly lower than did the control group. The 95% confidence interval on the mean difference ranges from -5.6 to -2.5 which means it is highly likely that the treatment lowered pain from betwen 2.5 and 5.6 points on the scale.
