A psychologist would like to examine the relative effectiveness of three different therapy techniques for the treatment of mild phobias. A sample of 15 individuals who display moderate fear of spiders were recruited to participate in the study. These individuals were then randomly assigned (n = 5) to one of the three different therapies. After six weeks of therapy each participant’s fear of spiders was evaluated, scores ranged from 1 to 5 (1 = no fear, 2 = some fear, 3 = neutral, 4 = afraid, 5 = extremely afraid). Use the data below to determine if the three therapies differed in how effectively they treated the participant’s fear of spiders. **Report the observed value of F to 4 decimal places.

10. When administering supplemental oxygen to a hypoxemic patient with a chronic lung disease, you should: A) recall that most patients with chronic lung diseases are stimulated to breathe by increased carbon dioxide levels. B) adjust the flow rate accordingly until you see symptom improvement, but be prepared to assist his or her ventilations. C) begin with a low oxygen flow rate, even if the patient is unresponsive, because high-flow oxygen may depress his or her breathing.D) avoid positive-pressure ventilation because the majority of patients with chronic lung disease are at increased risk for lung trauma.
