Suppose that a random variable X has only two values, 0 and 10. If P ( X = 0 ) = 0.5 , then what can we say about the expected value of X , E ( X ) ? There is not enough information to answer the question. E ( X ) = 5 E ( X ) = 10 E ( X ) = 0 E ( X ) = 0.5 .

Suppose that Carlos prefers current consumption to future consumption. Thus, Carlos is said to have a low time preference. Consider a country where life expectancy is 95 years. Two citizens, Carlos, 89 years old, and Deborah, 44 years old, are relatively healthy for their ages. 1: Assuming that Carlos and Deborah maximize their life-time consumption, which of the following statements is most plausible, all else equal? a. Carlos has a much lower time preference than Deborah has. b. Carlos and Deborah are indifferent between saving for the future and current consumption. c. Carlos and Deborah have very similar time preferences. d. Carlos prefers current consumption to future consumption to a greater degree than Deborah does. .

Students at a major unlversity in Southern California are complaining about a serious housing crunch. They say that many of the unlversity's students have to commute too far to school because there is not enough housing near campus. University officials perform a study, which is reported in the school newspaper, The report contains the following histogram summarizing the commute distances for a sample of 48 students at the university. Based on this histogram, estimate the standard deviation of the sample of 48 distances. Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place. (If necessary, consult a list of fomulas.) .
