3. In the long run, anqual real returns on common stocks have been normally distributed with mean 10% and standard deviation of 26%. Andrew plans to retire in 45 years and is considering investing in stocks. Answer the following questions assuming that these patterns of variation are expected to continue in the future. A. What is the probability that annual returns on common stocks next year will show a loss (that is, returns will be less than 0%)? B. Andrew thinks the width of the sampling distribution can be used as a measure of risk. What is the standard deviation of the sampling distribution of returns on stocks over the next 45 years? C. What is the probability that the mean annual return on common stocks over the next 45 years will show a loss (that is, the return will be less than 0%)? D. Explain in a few sentences why the results above imply long-term investing is less risky than short-term investing.

Exponential distribution is used to predict how long it will take for an event to occur in the future. For example: the time between two customers coming to a bank, the time until an equipment breaks down, or how long after the next Istanbul earthquake will occur. The average time between two phones coming to a workplace corresponds to an exponential distribution of 15 minutes. What is the probability that the first call will arrive within 5 to 8 minutes after the workplace opens on Monday morning? (Guidance: Investigate the relationship between the exponential distribution and the Poisson distribution.)
