Assume you have a one-year investment horizon and are tying to choose among three bonds. All have the same degree of defautt risk and mature in 9 years. The first is a zero-coupon bond that pays $1,000 at maturty. The second has a 71% coupon rate and pays the $71 coupon once per year. The third has a 91% coupon rate and pays the $91 coupon once per year. Assume that all bonds are compounded annually a. If all three bonds are now priced to yield 7.1% to maturity, what are their prices? (Do not round intermediate calculations, Round your answers to 2 decimal places.) b. If you expect their yields to maturity to be 71% at the beginning of next year, what will their prices be then? (Do not round) intermediate calculations. Round your answers to 2 decimal places.).

- Assume you have a population of 29000 people where 2% of the population has some particular disease. List the given numeric information along with the correct symbols. =29000=2%a) If you take a sample of size 44 , can we say that the sampling distribution of p is approximately normal? Why or why not? Check conditions: 1. np= which 2. n(1p)= 3. and N=Can we say that the sampling distribution of p is approximately normal in this case? (If the answer is no, state the first conditions in the list above that failed)b) Redo part a assuming p has increased to 90%. Check conditions: 1. np= which 2. n(1p)= 3. and N=Can we say that the sampling distribution of p is approximately normal in this case? (If the answer is no, state the first conditions in the list above that failed) Select an answer ) Yes, since all 3 conditions check out population where p is 2%, can we sa dis No, since the first condition did not check out No, since the second condition did not check out No, because the third condition did not check outc) If you take a sample of size 542 from the original population where p is 2%, can we say that the sampling distribution of p is approximately normal? Why or why not? Check conditions: 1. np= which 2. n(1p)= 3. and N=Can we say that the sampling distribution of p is approximately normal in this case? (If the answer is no, state the first conditions in the list above that failed) d) 12 people in it.d) Redo part c assuming the population only has 9212 people in it. Check conditions: 1. np= which 2. n(1p)= 3. and N=Can we say that the sampling distribution of p is approximately normal in this case? (If the answer is no, state the first conditions in the list above that failed) as large enough to use the normal distribue) In the last section a sample size of at least 30 was large enough to use the normal distribution to compute probabilities. How are the problems in this section different? Select an answer Select an answer The variable information collected from each individual is now qualitative instead of quantitative The variable information collected from each individual is now quantitative instead of qualitative It does not matter what variable information is collected from each individual, the conditions to check are always the same
