Empathy means being able to understand what others feel. To see how the brain expresses empathy, researchers recruited 16 couples in their midtwenties who were married or had been dating for at least two years. They zapped the man's hand with an electrode while the woman watched, and measured the activity in several parts of the woman's brain that would respond to her own pain. Brain activity was recorded as a fraction of the activity observed when the woman herself was zapped with the electrode. The women also completed a psychological test that measures empathy.

Solve the problem. At the Jumping Jack cookie factory, quality assurance inspectors remove broken or otherwise defective cookies from a moving conveyor belt prior to packaging. Based on past studies, the plant manager knows that the inspectors eliminate 98% of the defective cookies at a conveyor belt speed of 9 feet per minute. As the belt speed increases, the factory can produce more cookies per hour, but at the cost of lower quality of the packaged product. Inspectors collect only 60% of defective cookies at a belt speed of 18 feet per minute.

Use the figure to the right, which shows the percentages of adults from several countries who favor building new nuclear power plants in their country. The survey included random samples of 1051 adults from Country A, 1120 adults from Country B, 1048 adults from Country C, and 1013 adults from Country D. At a=0.05, can you support the claim that the proportion of adults in Country B who favor building new nuclear power plants in their country is different from the proportion of adults from Country C who favor building new nudear power plants in their country? Assume the random samples are independent. Country A 53% Country B 47% Country C 46% OCountry D 34% Identify the claim and state Ho and H- The claim is "the proportion of adults in Country B who favor building new nuclear power plants in their country is different than the proportion of adults from Country C who favor building new nuclear power plants in their country."

A medical researcher tested a new treatment for poison ivy against the traditional ointment. He concluded that the new treatment is more effective. Explain what the P-value of 0.037 means in this context. Explain what the P-value of 0.037 means in this context. O A. There is a 3.7% difference between the effectiveness of the new treatment and the effectiveness of the traditional ointment. O B. If there is no difference in effectiveness, the chance of seeing an observed difference this large or larger is 3.7% by natural sampling variation. O C. If there is a difference in effectiveness, the chance of seeing an observed difference this large or larger is 3.7% by natural sampling variation. D. There is a 3.7% chance that the new treatment is effective.
