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.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

statistic question 4

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 dlips designed to evoke laughter. During the laughing period, the
researchers measured the heart rate (beats per minute) of each subject, with the
following results: x = 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.
