Homework Answers
here since the test is directional and is greater than cutoff value,. it imply it is a right tailed test
for 0.05 level; cutoff z score for right tailed test =1.64

show all work. say a researcher is interested in testing the effectiveness of a new stress reduction method. She thinks, or predicts based on previous research, that the new method should reduce stress. one randonmly selected person (our subject) is trained in this method and his stress is measured (low values mean low stress). It is known that stress level of people in the general population has a mean of 40 and a standard deviation of 10. the score of...
