A physician wants to perform a study at a local health center
where 250 individuals have stress issues. The purpose of the study
would be to determine if doing yoga for 30 minutes helps with
improving stress levels compared to sleeping for 30 minutes.
Part A: Describe an appropriate design for the
study. (5 points)
Part B: The hypotheses for this study are as
follows:
H0: There is no difference in the mean improvement of
stress levels for either treatment.
Ha: The mean improvement of stress levels is greater for
the yoga treatment.
The center will allow individuals to do yoga during visits if the
null hypothesis is rejected. What are the possible Type I and II
errors? Describe the consequences of each in the context of this
study and discuss which type you think is more serious. (5
