To study the effect of type of music on concentration, 30 OSU Public Health majors were assigned at random into two groups (15 students in each group). Subjects in one group listened to rock music on headphones while trying to memorize a list of vocabulary words, while the subjects in the other group listened to baroque music on headphones while trying to memorize the same list of words. The number of words correctly memorized was recorded. a) (1 point) What is the response variable (variable of interest)? (1 point) What is the treatment in the experiment? (1 point) What are the experimental units? (2 points) Is there replication in this experiment? If 50, describe the replication. (2 points) The baroque group was able to memorize 82% of the words, while the rock group only memorized 50% of the words. Can we say the type of music caused the difference in memorization? Why or why not
