A therapist wants to study the effects of yoga and
meditation on stress relief. She has 60 volunteers who
experience varying levels of stress. She believes that
the volunteers' professions could have an effect on the
results. A preliminary survey reveals that 22 of the
volunteers are in high-stress professions. The therapist
randomly assigns 11 of these subjects to practice yoga
and the remaining 11 to practice meditation. Nineteen of
the other 38 volunteers are randomly assigned to
practice yoga and the remaining 19 to practice
meditation. Before the experiment begins, all the

participants will be asked to rate their stress levels on a
scale of 0 to 10, with 0 representing "no stress" and 10
representing "highest level of stress." At the end of one
month, the subjects will be asked to rate their stress
levels again. The differences in stress levels will be
compared for the different stress-relieving activities
within the two types of professions.
