One unit of A is composed of two units of B and three units of C. Each B is composed of one unit of F. C is made of one unit of D, one unit of E, and two units of F. Items A, B, C, and D have 10, 60, 60, and 25 units of on-hand inventory, respectively. Items A, B, and C use lot-for-lot (L4L) as their lot-sizing technique, while D, E, and F require multiples of 60, 110, and 90, respectively, to be purchased. B has scheduled receipts of 30 units in Period 1. No other scheduled receipts exist. Lead times are one period for Items A, B, and D, and two periods for Items C, E, and F. Gross requirements for A are 10 units in Period 1, 20 units in Period 2, 60 units in Period 6, and 40 units in Period 8.

2. Earlier in this chapter, we discussed that iron supplements are popular in part because they raise oxygen levels in our bodies, and increased oxygen levels help us feel more energetic. We also said that consuming an iron supplement with a drink high in Vitamin C enhances the effects of the iron supplement. A researcher has a sample of 40 people randomly assigned to two factors: iron supplement and Vitamin C consumption. Specifically, people were randomly assigned either to take an iron supplement or not to take an iron supplement. In addition, people were also randomly assigned either to consume a glass of orange juice (which is high in Vitamin C) or not to consume a glass of orange juice. The researcher uses a pulse oximetry to measure oxygen levels as the dependent variable (to keep the calculations simple, we are using intentionally hypothetical numbers for oxygen levels).The data is presented below. Carry out the analysis of variance using SPSS and determine whether there are any main effects or an interaction. Make a line graph of the results and interpret the pattern of the results.

1. The firm's tax rate is 40%. 2. The current price of Legacy’s 10% coupon, noncallable bonds with 10 years remaining to maturity is $1,100.00. Legacy does not use short-term interest-bearing debt on a permanent basis. 3. The current price of the firm’s 8%, $100 par value, perpetual preferred stock is $114.00. 4. Legacy’s common stock is currently selling at $45 per share. Its last dividend (D0) was $3.00, and dividends are expected to grow at a constant rate of 6.0% in the foreseeable future. Legacy’s beta is 1.1; the yield on T-bonds is 6.0%; and the market risk premium is estimated to be 5.5%. For the over-own-bond-yield-plus-judgmental-risk-premium approach, the firm uses a 4.0% judgmental risk premium. 5. Legacy’s capital structure is 40% long-term debt, 10% preferred stock, and 50% common equity.

What is the market interest rate on Legacy’s debt, and what is the component cost of this debt for WACC purposes?

2 The Backstory Amazon.com wants to try out it’s new ‘Delivery by Drone” service and has recruited you to write a Java console application to calculate the shipping cost. They are going to charge the customer based on various criteria, as shown below:

Amazon Prime members get a 10% discount.

3 Specifications

• First, ask for the weight of the package (in kilograms). The user can enter this as a decimal number, so use type double. Values of 0 or less are invalid (i.e. a package has to weigh something). Do not accept weights of more than 20 Kg either, as this is the maximum weight the company will ship).

• If the user enters an invalid choice, print an appropriate error message and abort the program. (See sample outputs for error messages).

• Now ask the user to enter the distance to ship the package (in miles). This will be entered as an integer. 0 miles or less is considered invalid (must be a positive distance to ship). Also, do not accept distances of more than 3000 miles - consider 3000 miles to be the company’s maximum shipping distance.

• If the user enters an invalid choice, print an appropriate error message and abort the program. (See sample outputs for error messages).

• For a valid weight and distance, compute the shipping charges according to the chart above, noting that ”rate per 50 miles shipped” means that anything up to 50 miles is at the 50 mile rate, anything above 50 up to 100 miles is at the 100 mile rate, and so on.

• Ask if the user is an Amazon Prime member. If the user says Yes, give them a 10% discount.

• Print out the following results: – The package weight (default format), in kilograms. – The shipping rate for this package, to 2 decimal places, (money format). – The number of miles chosen. – The calculated shipping cost, to 2 decimal places (money format).

• See the Sample Runs below for expected output messages and numerical output formats.

• Also note: The System library has a method called exit(), which will cause a program to terminate immediately. It requires a parameter - usually, it is sufficient to just pass in the value 0

Determining if a column’s data functionally determines another column’s data can usually be accomplished by asking the question “Can X have only one Y or can it have more than one Y?” An example might be “Can a doctor have only one patient or more than one patient?” If the answer is only one, then doctor functionally determines patient, otherwise, if a doctor can have more than one patient, the doctor does not functionally determine the patient. In other words, if doctor functionally determines patient, then if you know the doctor, you can know the one and only patient he/she has. If doctor does not functionally determine patient (which of course it doesn’t), then you can’t just talk about the doctor and his/her patient. You have to specify the patient. This means that the key would have to include both doctor and patient.

5.) Is the following true? Why or why not? Doctor, Patient -> Prescription

6.) Is the following true? Why or why not? Doctor, Patient, Prescription -> Refills Remaining Sometimes a key that is made up of more than one attribute (like Doctor, Patient) can technically functionally determine another attribute (like the Patient’s birth date). But it is also true that you don’t need Doctor in order to functionally determine a Patient’s birth date. This situation is what 2NF is all about. Making sure that all functionally determined attributes need all of the key columns to functionally determine them. In cases where you don’t, you need to decompose the related data into two or more tables. One for the full key (and any attributes you need the full key to determine), and one for each attribute that is only determined by a part of they key (along with that part of the key). For example, if you had: Doctor, Patient -> Last Appointment Date and Time, Patient Birth Date You would want to create two tables. One for: Doctor, Patient -> Last Appointment Date and Time And one for: Patient -> Patient Birth Date The problem this solves is that if a patient is seeing more than one doctor (perhaps a general practitioner and a neurologist), you don’t have to duplicate the patient’s birth date for each doctor he/she visits. This is redundant, and additionally makes it possible for the “two” birth dates to differ in the database when clearly a person doesn’t have two birth dates.

7.) Should the following design be decomposed into two or more tables? Why or why not? And if decomposing, what columns belong in each resultant table? Patient, Hospital Room Number -> Hospital Floor

8.) Should the following design be decomposed into two or more tables? Why or why not? And if decomposing, what columns belong in each resultant table? Doctor, Patient -> Hospital Admit Date and Time, Doctor’s Pager # Sometimes a key can technically functionally determine two attributes but does so transitively. An example would be: Employee -> Employee’s Boss, Employee’s Boss’s Email Address The problem is that a boss likely has several people that report to them. So, if everywhere we record an employee’s boss, we also record their boss’s email address, it’s possible that the same boss might appear to have different email addresses when looked up by one employee vs. another. Solving this problem is what 3NF is all about. Again, this is not just about reducing redundancy but also reducing the chance for inconsistent data. To solve this problem, we’d want to decompose the design into two tables: Employee -> Employee’s Boss Boss -> Boss’s Email Address Aside: This decomposition is sufficient to meet the requirements of 3NF. However, an even better design would involve realizing that a boss is also an employee and store all employees in one table and have the relationship between employee and boss recursively refer to other rows in the same table: Employee -> Employee Email Address, Boss The Boss attribute would refer to the Employee column of another row in that same table.

9.) Should the following design be decomposed into two or more tables? Why or why not? And if decomposing, what columns belong in each resultant table? Doctor -> Department, Department Office Location (Note: a department can have only one office location)

10.) Should the following design be decomposed into two or more tables? Why or why not? And if decomposing, what columns belong in each resultant table? Doctor, Patient, Date and Time -> Diagnosis, Typical Prognosis (By Typical Prognosis, assume of the diagnosis in general, not the particular doctor diagnosing the particular patient.)
