a) A study recruits participants and measures their levels of physical activity and self- reported stress levels. b) A research project investigates the impact of a new workout program on participants' body mass index (BMI). Participants are randomly assigned to either the new program or a control group. c) Researchers observe a group of individuals engaging in different types of exercise routines and examine their reported levels of happiness. d) A study surveys 100,000 people to ask them about their hours of sleep and their academic performance. e) A study observes the behavior of children in a preschool classroom to see if there is a relationship between the amount of time they spend on screens and their attention spans. Identify the variables (dependent/independent), and research design type (correlation/experimental) for the following studies:
