Answer to Question #15335 in Statistics and Probability for Francie
3. A researcher is interested in whether listening to music helps or hinders test-performance. To control for differences in cognitive level, this researcher decides to use a within-participants design. He selects a random sample of participants and has them study different material of equal difficulty in both the music and no music conditions. Participants take a 20-item quiz on the material. The table below shows the scores on the quiz. The study is completely counterbalanced to control for order effects. The scores obtained are measured on an interval-ratio scale and are normally distributed.

Once again, excellent work. Their high quality of work and reasonable price allowed me to focus on studying for a test instead of having to come up with extemporaneous lab work that is several chapters ahead of where the test is.
Would highly recommend their work.
