The obesity rates of elementary age children living in urban areas are compared to those living in rural areas to see whether children in urban settings have higher obesity rates. A group of cancer patients is randomly assigned into one of two groups. One group is given a new drug to flight the side effects of chemotherapy and the other group does not receive the frequency and severity of their side effects to see whether the new drug improved the overall negative side effects of chemotherapy. The smoking rates of teens in urban areas are compared to those living in rural areas to see whether teens living in rural settings have higher rates of smoking. A group of students is randomly assigned into one of two groups. One group listen to classical music while taking a math test and the other group takes the test in silence. The average test scores of the two groups are compared to see whether listening to music during a math test has an effect on scores. "People with diabetes are at higher risk for certain cancers than those without the blood sugar disease, suggests a new study based on a telephone survey of nearly 400.000 adults." A recent study concluded that babies who breastfeed are less likely to grow into children with behavioral problems by the time they reach ago 5 than these who receive formula milk. Identify the sampling technique used to obtain each sample. A deck of cards is shuffled and a card is drawn at random. An education researcher randomly selects 38 schools from one school district and interviews all the teachers at each of the 38 schools. Identity the typo of sampling used in this example. At a college there are 120 freshmen. 90 sophomores, 110 juniors, and 80 seniors A school administrator selects a random sample of 12 of the freshmen, a random sample of 9 of the sophomores, a random sample of 11 of the juniors. and a random sample 8 of the seniors. She then interviews all the students selected. Identity the type of sampling used in this example. The first 10 people to arrive at a town meeting are surveyed to find out their opinion proposed bond referendum.
