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.

Student Absences and Grades on the Final Exam Dr. V. noticed that the more frequently a student is late or absent from class the worse he or she performs on the final exam. He decided to investigate. Dr. V. collected a random sample of 22 students. This sample includes the number of times a student is absent and their grades on the final exam. The data can be found in the Excel file Assignment10.xlsx. Do not use any software that I did not assign. Question 1: Which or the two variables (times absent or grades on the final exam) is the independent variable and which is the dependent variable?
