"A researcher investigated the short-term effect of including classical music on the standard relaxation therapy used in the treatment of smoking. The researcher investigated whether slow classical music when included with relaxation therapy has any significant effect on the behavior of smoking cigarettes. The slow classical music used with the therapy is the “Piano Concerto in A minor” by Edvard Grieg. A piano concerto is a type of concerto, a solo composition in the classical music genre, which is composed for a piano player and is typically accompanied by an orchestra or other large ensemble. Participants who smoked at least one pack of cigarettes a day (20 cigarettes in a pack) were randomly assigned to one of two groups. The participants in condition one received relaxation therapy that included classical music. The second condition consisted of participants who served as a control group and were given the same relaxation therapy but did not include the slow classical music. The number of cigarettes smoked two days later is recorded for all participants. The data are presented below. Test at alpha level .01" How many Independent variables are there, what are they?
