A sports physiologist was interested in whether extended periods of jogging reduce the resting pulse rate. A random sample of accounting majors (none of whom had ever been involved in jogging) was selected from the senior class at a large university. Resting pulse rates were taken on every subject at the following intervals: first, before starting the jogging program; second, after 4 weeks of the program; third, after 8 weeks; and finally, after 12 weeks. Is there a difference in pulse rate by time? Question 23 (1 point) What is the INDEPENDENT variable? Question 23 options: jogging time accounting majors pulse rate Question 24 (1 point) What is the DEPENDENT variable?
