An experiment was conducted to test whether classical music helps with mathematical performance. To study this, participants (n=9) were given an algebra test. Half of the sample completed the test in a room with classical music playing while the other half completed it in a room with no sounds at all. After a brief rest, the two groups switched rooms and completed a slightly modified version of the algebra test. Thus, all participants experienced both conditions. The scores for the two conditions were then compared, showing that listening to classical music did help mathematical performance by an average of MD =2 points with SS =32. a. Calculate the estimated standard error. b. Compute the t statistic and state the conclusion of these findings.

What is the correct conclusion given a=0.05? O Because the P-value is less than a=0.05, the student should reject Ho. O Because the P-value is less than a=0.05, the student should reject Ho. O Because the P-value is greater than a=0.05, the student should reject Ho: O Because the P-value is greater than a=0.05, the student should fail to reject Ho.
