Laughter is often called 'the best medicine' since studies have shown that laughter can reduce muscle tension and increase oxygen in blood. 90 subjects (18-34 years old) watched film dips designed to evoke laughter. During the laughing period, the researchers measured the heart rate (beats per minute) of each subject, with the following results: j = 73.5, s = 6. It is well known that the mean resting heart rate of adults is 71 beats per minute. Setup a hypothesis testing whether the true mean heart rate during laughter exceeds 71 beats per minute. Create an appropriate test at the alpha 0.05 level of significance.
