Researchers asked parents of 19 American children, ages 8 to 12, to complete surveys on the number of hours their children spent reading and the number of hours they spent on screen-based media time. Each of the children also underwent magnetic resonance imaging (MRI) to assess connectivity in the brain. More time spent reading was associated with higher connectivity, while more screen time was associated with lower connectivity in the brains of the children. 1. What is the sample in this study? c 2. What is a possible population? F6 3. Is this an experiment or an observational study? Why did you make that decision? 4. Can we conclude that more time spent reading increases connectivity in children's brains? 5.
