Jane kept a plant on a table next to her stereo. She noticed that her plant seemed to grow more when she played music for it. Based upon this observation she hypothesized that music causes plants to grow faster; therefore, plants exposed to music should grow more over a given period of time than those that are not. To test her hypothesis and prediction she took two identical plants and put them in identical rooms with identical stereos, the same temperatures, soil and lighting conditions, and gave them the same amount of water. She then played music in only one of the rooms and recorded the results (plant growth) over a month’s time.What is the experimental (independent) in this experiment?

The battery packs used in electric and hybrid automobiles are one of the largest cost components for manufacturing these cars. As the price of these batteries decline, we expect that the

Refer to the graph below. If the horizontal line on the graph represents a price floor, then the price floor is

Consider the diagram below, in which the consumer is initially maximizing utility at point A. When the price of food falls, she moves to point B. If, hypothetically, after the price change, her income was decreased to return her to her old indifference curve, she would choose point D.   Which of the following statements is accurate?

A firm is currently producing 100 units of output using labor and capital. The marginal product of labor is 60 and the marginal product of capital is 20. The price of labor is $10 and the price of capital is $100. Is the firm minimizing the long-run cost of producing 100 units of output? If so, explain how you know. If not, explain the adjustment the firm should make to produce 100 units of output at a lower cost. In either case, draw a carefully labeled isoquant/isocost diagram to illustrate your answer.
