1. Direction: During the recent tour the France, the world's best known athlete bicycles race. some cyclists have been expelled for attempting to enhance their performance by 'blood doping' with a synthetic hormone, erythropotein (EPO), that stimulates the production of oxygen-bearing (and fatigue inhibiting( red blood cell. Assume that a mental health investigator at a large clinic wants to determine whether EPO. viewed as a potential therapeutic tool, might increase the endurance of severely depressed patients. Volunteer tients are randomly assigned to one of the two groups, a treatment group xl thgt receive a prescribed amount of EPO and a control group that receives an harmless neutral substance. Subsequent endurance scores are based on the total of time, in minutes, that each patients remains on a rapidly moving treadmill. The statistical score focuses on the difference between means endurance score for the treatment and control groups 10 l 16 13 a) Formulate the research question b) Formulate the statistical hypothesis (hint: Make sure to include the null and alternate hypotheses c) Write the decision rule d) Write the calculation by showing your work e) Write your decision 1) Write the interpretation
