3. Susan Sound predicts that students will learn most effectively with a constant background sound, as opposed to an unpredictable sound or no sound at all. She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10 point multiple choice test over the material and the results is given below: group test scores 1) constant sound 7 46866 2 9 2) random sound 5 5 3 4 47 2 2 3) no sound 2 47 12 15 5 Construct the ANOVA table below and test at 5% if Susan's prediction is correct? Use the five step procedure.
