2. A scientist read an article in a magazine about how air pollution can cause children to develop asthma. Since the article did not come from a peer-reviewed magazine, he doubted the claim,
instead believing that children living in a smog-filled city would not have an increased chance of
developing asthma He wanted to test his own idea, so he formed a hypothesis and planned out
an experiment. The scientist decided to compare 10th graders from three schools in smog-filled
cities to 10th graders from three schools in smog-free rural areas. He found out how many of
these students had asthma and recorded his data in the table below. After looking at the results,
he was amazed at what a big risk factor living in a smog-filled city was after all. (20 points)
