A therapist specializes in treating children with a fear of the dark. She believes leaving a nightlight on and having the parent “check the room” before bedtime will reduce the children’s fear. She designs a 2 x 2 study and randomly assigns each child to a nightlight condition (yes or no) and to a “parent room-check” condition (yes or no). Each child is assigned to one condition. Based on the information provided: List the main effect(s) and interaction(s) possible for this study. Is this an independent groups, arepeated measures, or a mixed factor design…and how do you know this? What is a third factor that might also influence children’s fear?
Lucy, a real estate developer, collected data on 300 residential properties, recording whether each home had 4+ bedrooms or 1 - 3 bedrooms. Lucy also recorded whether each property was on a large lot (defined as at least 16,000 sq. feet) or a small lot (fewer than 16,000 sq. feet). The probabilities are reflected in the partially-completed tree diagram: # Bedrooms Lot Size B Large 4+ BR 0.41 0.32 Small A 0.17 Large 1-3 BR C Small a. The values labelled A, B and C represent the probabilities of their respective branches of the tree diagram. What are these values? A = B = C = b. Given that a randomly selected home has four or more bedrooms, what is the probability that the home is on a large lot? c. What is the probability of randomly selecting a home that has 4 or more bedrooms and is on a small lot? d. What is the probability of randomly selecting a home that is on a large lot?

6 a-c. Even though a person may only need to consume 1-2 liters of water per day, many poor countries do not have the infrastructure* to provide reliable safe drinking water to their population. *do not have enough capital to build sufficient sewerage facilities for treating human and animal waste, or water distribution systems for separating supplies of safe drinking water from rivers used for sewerage disposal (e.g., deep wells or piping water to homes from uncontaminated sources) (a) Over the long run, would it be cheaper to provide bottled water for everyone than to use the money to build infrastructure? Explain how you would support your answer, referring to information found on steps that are being taken to provide safe drinking water in poor countries. [Note: This question refers to the cost of different methods of distributing water for longterm critical needs, not the issue of how to dispose of plastic bottles.] (b) Find out the price per gallon of the largest bottle of water you can purchase at a local supermarket, and compare this to the price per gallon of tap water (you can find this on the website of the utility that supplies your community with water, or look up the typical price per gallon of tap water in the US). (c) What accounts for most of the cost of bottled water, and indicate where you found this out?
Problem 9-07 You are analyzing the U.S. equity market based upon the S&P Industrials Index and using the present value of free cash flow to equity technique. Your inputs are as follows: Beginning FCFE: $80 k=0.11 Growth Rate: Year1-3: 11% 4-6: 10% 7 and beyond 9% a. Assuming that the current value for the S&P Industrials Index is 4,600, would you underweight, overweight, or market weight the U.S. equity market? Do not round intermediate calculations. Round your answer to the nearest cent. You should -Select- the U.S. equity market as the estimated value of the stock of $ IS -Select- the S&P Industrials Index. b. Assume that there is a 2 percent increase in the rate of inflation what would be the market's value, and how would you weight the U.S. market? Assume that the required return would increase from 11% to 13%, decreasing the value. Also assume that the nominal cash flow growth rates would increase for all time periods by two percentage points. Do not round intermediate calculations. Round your answer to the nearest cent. You should -Select- the U.S. equity market as the estimated value of the stock of $ IS -Select- than the S&P Industrials Index.
