If sample was lost during the heating process, would the mass of water lost be too high or too low? Would this experimental error result in a value of n that is too large or too small?

If some water remained at the end of the heating process, would the calculated mass of water lost be too high or too low? Would this experimental error result in a value of n that is too large or too small?

**BY HAND** For the Data Below, please do the following:

State the null and alternative hypotheses. (2 points)

Construct an ANOVA table (20 pts)

Determine whether your results are significant (1 points)

Do a post hoc analysis (using Tukey’s HSD), if necessary (5 points)

State your conclusions in one or two sentences. (2 points)

A survey was done in a community in which residents were asked if they felt that family planning counseling was needed in the community. The tabulation in the accompanying table gives the opinions and the number of children of the respondents. Determine whether there is a difference in mean number of children of respondents. Make sure you follow all the steps of hypothesis testing.

An investor has two bonds in his portfolio that have a face value of $1,000 and pay a 12% annual coupon. Bond L matures in 20 years, while Bond S matures in 1 year.

1. What will the value of the Bond L be if the going interest rate is 7%, 8%, and 13%? Assume that only one more interest payment is to be made on Bond S at its maturity and that 20 more payments are to be made on Bond L. Round your answers to the nearest cent.

   	7%	8%	13%
   Bond L	$	$	$
   Bond S	$	$	$

2. Why does the longer-term bond’s price vary more than the price of the shorter-term bond when interest rates change?
   1. Long-term bonds have lower interest rate risk than do short-term bonds.
   2. Long-term bonds have lower reinvestment rate risk than do short-term bonds.
   3. The change in price due to a change in the required rate of return increases as a bond's maturity decreases.
   4. Long-term bonds have greater interest rate risk than do short-term bonds.
   5. The change in price due to a change in the required rate of return decreases as a bond's maturity increases.

An investor has two bonds in his portfolio that have a face value of $1,000 and pay a 12% annual coupon. Bond L matures in 17 years, while Bond S matures in 1 year.

Question 8 options:

A steel product is manufactured by starting with raw material (carbon steel wire) and then processing it sequentially through five operations using machines A to E, respectively (see table below). This is the only use that the five machines are put to. The hourly rates for each machine are given in the table. Answer the following questions. Use the original output rates to answer each question (i.e., disregard any changes mentioned in previous questions).

Consider the following questions.

a. What is the maximum output per hour of the steel product?

b. By how much would the output be improved if B was increased to 50?

c. By how much would the output be improved if C was increased to 40?

d. By how much would the output be improved if C was increased to 50?

e. What is the effect on the system if machine A can only manage an output of 20 in one hour?

f. What is the effect on the system if machine C can only manage an output of 20 in one hour?

g. What is the effect on the system if machine B is allowed to drop to an output of 20 in one hour?

1. Table A gives investments, NPVs, IRRs and the first three years’ cash flow for several capital investment projects. Each project’s cash flows continue for several more years, longer for some projects than others. The cost of capital is 12% for all projects.

Table A (figures in millions).

Projects A and B are mutually exclusive - your firm can take only one. The projects are discrete - you cannot make partial investments in any project.

1. Which project would you choose, A or B?
2. Suppose that the firm now identifies a new project AA with exactly the same cash flows, NPV and IRR as project A. Does the opportunity to invest in AA change your answer to part c?
3. Suppose the firm has only $200 million to invest - a fixed capital constraint. Which projects would you undertake? (Ignore project AA.)
4. Now the firm negotiates a line of credit that allows it to borrow up to $100 million at 8%. Would access to additional debt capital at a cost of 8% change your answers to questions c, d or e?

C. 50% of the energy passed on to the next step while 50% is lost as heat  

D. 100% of the energy passed on to the next step

A. they are made of carbon.   B. they create carbon.

C. they destroy carbon.           D. they store carbon.
