15. Students in a large statistics class were randomly divided into two groups of 20 each. The first group took the midterm exam with soft music playing in the background while the second group took the exam with no music playing. The average scores of the two groups on the exam were compared. (a) Describe how random assignment could be done using technology. Be specific. (b) Create an outline showing how the researchers could carry out a completely randomized design for this experiment. (c) Suppose the results of the experiment showed that there was a statistically significant difference in the average scores of the two groups. Explain what statistically significant means.
