500 randomly selected university students were selected for a study on smoking status and stress levels. At the time of the study, students were asked to rate their stress levels on a scale of 0 - 100 with O indicating no stress. Students were also asked to disclose whether they were a non-smoker, a light smoker, or a heavy smoker. Of the 500 students, 75 identified themselves as heavy smokers, 150 identified themselves as light smokers, and 275 identified themselves as non-smokers. The average stress level reported for heavy smokers was 60.4. The average stress level reported for light smokers was 45.7. The average stress level reported by non-smokers was 56.6. Based on these results, which of the following statements is true? On average, heavy smokers have stress values of 3.8 times the stress levels of non-smokers On average, heavy smokers have stress values of 3.8 less than non-smokers On average, heavy smokers have stress values of 3.8 times less than the stress levels of non-smokers On average, heavy smokers have stress values of 3.8 greater than non-smokers
