One class of N = 16 students who listens to calming music each day while working on arithmetic problems is chosen as the experimental group (group 1). Another class of N = 16 students serves as a control group with no music (group 2). Accuracy scores are measured for each child, and the average for students in the music condition is X = 86.75 with SS = 1250. For the no-music condition, the average is X = 78.8, with SS = 1180. A) Compute a 95% confidence interval for u1 - 2, the population mean difference in accuracy scores. For this sample, t*df = The 95% CI = ( NOTE: Report t*df exactly as it is in the PsyStat calculator.
