Mostafa was studying whether CBT was effective at alleviating fear of flying on airplanes. He recruited 11 participants who have listed themselves as nervous flyers. Six underwent CBT, and five had no therapy. All 11 boarded a short flight and had their heart rate monitored as a measure of nervousness. Does Mostafa have evidence that CBT alters anxiety while flying? Note for this question, you can skip assumptions, tests of assumptions, outlier analysis, and a figure. Include the hypotheses, conclusion, and analyses (with all your work shown).
