Please answer photo 1 is just for reference Laughter is often called "the best medicine," since studies have shown that laughter can reduce muscle tension and increase oxygenation of the blood. To determinethe physiological changes that accompany laughter, 25 subjects (18-34 years old) watched film clips designed to evoke laughter. During the laughing period, theresearchers measured the heart rate (beats per minute) of each subject and reported a sample mean of 73.5 and sample standard deviation of 6.
