1. ABC Inc.’s currently outstanding 9% coupon bonds have a yield to maturity of 8%. ABC believes it could issue new bonds at par that would provide a similar yield to maturity. If its marginal tax rate is 30%, what is ABC’s after-tax cost of debt, rd?

Also, ABC can issue perpetual preferred stock at a price of $50 a share with an annual dividend of $3.00 a share. What is the company’s cost of preferred stock, rps?

Besides, ABC has a beta of 1.4. The long term risk-free rate is 6%, while the market risk premium is 5.5%, and the return on an average stock in the market last year was 14%. What is the estimated cost of common equity, re using the CAPM?

Finally, if the tax rate is 30% and ABC has a target capital structure of 40% debt, 5% preferred stock, and 55% common stock, what is its WACC?

Part 4:

1. A woman has been injured in an automobile accident and as a result is permanently disabled for life. (The accident was not her fault.) She is 35 years of age and had planned on working until age 70. As a potential college professor, she was about to start a job that paid $50,000 annually. Using 6%, what is the amount of lost income in present-day dollars?

2. Additionally, she faces annual medical bills of $30,000, all of which are related to the accident. Her life expectancy is age 85. Using 6%, what is the amount of the medical expenses in present-day dollars?

3. Also, during retirement she had planned on receiving $75,000 per year. What is the present-day value of the lost pension? Note: This part requires two calculations.

4. How much should she sue for in court in terms of damages and lost compensation ? Ignore attorney fees?

a.)What is meant by trait level and item difficulty in IRT? Provide an example with two items to illustrate. If an item has a difficulty level of 2.0, then what is trait level for someone who has a .50/.50 probability of getting it correct? Explain.

b.) Continuing with your example above, explain the three primary item parameters that could be modeled in IRT analyses. Clarify by explaining how your two items could be the same on one parameter but vary on another.

c.)Returning to question b.) demonstrate how 2 items with the same difficulty but different discrimination parameters can lead to different probabilities of a correct responses for individuals 1 standard deviation apart on the tested attribute? Show your work and explain the difference.

6. Morning House is a mail-order firm which carries a wide range of rather expensive art objects for homes and offices. It operates by advertising a particular item either in selected magazines or in a direct-mail program. Suppose the sales response varies widely by item and the firm’s management has been unable to predict in advance which items will sell well and which will not. Consequently, the firm frequently experiences either stock-outs or excessive inventories. For many of the products Morning House sells, it is possible to order a limited amount for inventory and to place a subsequent order for delivery within two weeks. Thus, if the firm could make a early prediction of the ultimate sales of a product, its inventory problems would be greatly reduced. Since it takes approximately six weeks to receive 90% of the response to a given campaign, an accurate prediction of total sales made as late as the end of the first week of receiving orders would be useful. The first week’s sales and total sales of the last 12 campaigns of the firm are shown below. Can the first week’s sales be used to predict total sales? * Need help on minitab if this is a regression?

                        First week’s   Total

Campaign      Sales               Sales

1        32                    167

Intro Topics Covered: Writing classes; References; Equality

B.O.S.S. is a service designed to provide a safe ride around campus. It runs seven days a week while school is in session and there is no cost to use this service.

For this assignment you will write a BossRoadTrip class and a driver class called BossRoadTripDriver. A BossRoadTrip object represents a trip that someone might take between two locations over couple of minutes. Here is the UML diagram for the BossRoadTrip class:

BossRoadTrip

- start: String

- destination: String

- minutes: int // at least 1

+ BossRoadTrip(start: String, destination: String) // minutes = 1, must call other constructor

+ BossRoadTrip(start: String, destination: String, mins: int)

+ getStart() : String

+ getDestination() : String

+ getMinutes() : int

+ lengthen(mins: int) : void // adds additional minutes to trip, mins supposed to be positive, if not do not add

+ shorten(mins: int):boolean //reduces minutes of trip, returns true if successful, false otherwise. //mins supposed to be negative, if not do not update the minutes instance variable. //if mins that will be taken from the trip will make minutes <1, you //should not update the trip length and you should return false

+ equals(other: Object) : boolean // true if all instance variables are equal

+ toString() : String // used to print trip data. Notice that it prints minute or “minutes”

The UML diagram for the BossRoadTripDriver class shown below. You must implement these classes the way that we specify. (Note: The comments in the UML class diagrams are not a standard part of UML. It just happens to be a convenient place to document some of how the methods should work.)

The BossRoadTripDriver combine() method needs a bit of explanation. It takes two BossRoadTrip objects as parameters and returns the combination of the two. This only makes sense if the destination of the first BossRoadTrip is the start of the second BossRoadTrip. When this is the case, the method returns a new BossRoadTrip whose start comes from “first” and destination comes from “second” and whose minutes are the sum of minutes from “first” and “second”.

When the two trips don’t match correctly, you signal this fact by returning a null reference. (There are better ways to handle this, but we havent covered the techniques yet.) You need to remember that the null value represents an undefined object. So, if try to call a method using null, your program will crash. This means that your main() method will have to check the return value of combine() to see whether it is null. Your driver program will ask the user to enter two BossRoadTrips. Then, it will ask if the user wants to adjust their trip duration(minutes). It will then compare for equality and try to combine them.

Boss Road Trip Driver

+ static main(String[] args) : void

+ static combine(first: BossRoadTrip, second:BossRoadTrip) : BossRoadTrip // returns a new BossRoadTrip that combines first and second // if trips can’t be combined, return value is null

+static createRoadTrip(Scanner stdIn, int tripNumber):BossRoadTrip //prompts the user for a series of values to define a new BossRoadTrip object; then //return the object created

+static modifyTripLength(stdIn: Scanner, tripNumber: int, trip: BossRoadTrip): void //prompts the user for an integer to modify the trip’s minutes variable; if the //user provides an integer >0, it calls the lengthen method on trip object, //and if <0 it calls the shorten method

You decided to purify a protein named Snow by using a buffer of pH 8. If the Snow is mixed with two other proteins named Danny and Tyrion, in the pH 8 buffer, and, if you perform an anion exchange chromatography, which one of them will exhibit the strongest binding to the column?

The PI of snow is 6

The PI of danny is 8

The pi of tyion is 10

C++ Programa that:

// 1) Ask the user to enter two numbers greater than zero. Store the

//    values into two variables named 'n' and 'm'.

//    Additionally, implement a while-loop to keep asking the user to enter

//    the numbers again if any of the two numbers are equal or smaller than zero.

// 2) If the two numbers (n, m) are equal, display the message "The

//    numbers are the same". If the two numbers are different, display

//    the message "The numbers are not the same".

// 3) Calculate and display the number n elevated into the power of m: n^m

//    Store the result into a variable named 'X'.

//    HINT: Use the pow() function.

//    EXAMPLE: If n = 3 and m = 2 then X = 3^2 = 3 * 3 = 9

//    EXAMPLE: If n = 2 and m = 3 then X = 2^3 = 2 * 2 * 2 = 8

//    EXAMPLE: If n = 5 and m = 1 then X = 5^1 = 5

//    EXAMPLE: If n = 1 and m = 3 then X = 1^3 = 1 * 1 * 1 = 1

// 4) The result from (c) is already stored into the variable 'X'.

//      Calculate and display the factorial for the value in 'X': X!

//    Store the result into a variable named 'factorial'.

//    HINT: Use a for-loop similar to the for-loop used to calculate the

//          mean of a sequence of numbers in the file 5.3-For.cpp. Instead

//          of adding numbers, now we want to multiply numbers.

//    EXAMPLE: If X = 9, then factorial = 9! = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 = 362880

//    EXAMPLE: If X = 8, then factorial = 8! = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 = 40320

//    EXAMPLE: If X = 5, then factorial = 5! = 1 * 2 * 3 * 4 * 5 = 120

//    EXAMPLE: If X = 1, then factorial = 1! = 1

//    NOTE: The calculation of a factorial can result in a really a big number,

//          and the compiler may give an incorrect result. Use the numbers

//          provided in the examples to test your code.

// 5) Add code to ask the user if he wants to quit the program. If

//    the user enter 'yes' the program exits, if the user enter 'no' or any

//    other string, the program will execute again.

You are the newly appointed assistant administrator at a local hospital, and your first project is to investigate the quality of the patient meals put out by the food-service department. You conducted a 10-day survey by submitting a simple questionnaire to the 400 patients with each meal, asking that they simply check off that the meal was either satisfactory or unsatisfactory. For simplicity in this problem, assume that the response was 1,000 returned questionnaires from the 1,200 meals each day. The results are as follows:

a. Determine the p⎯⎯p¯ , S_p, UCL and LCL based on the questionnaire results, using a confidence interval of 95.5 percent, which is two standard deviations. (Round your answers to 4 decimal places.)

The price of a share of stock divided by the company's estimated future earnings per share is called the P/E ratio. High P/E ratios usually indicate "growth" stocks, or maybe stocks that are simply overpriced. Low P/E ratios indicate "value" stocks or bargain stocks. A random sample of 51 of the largest companies in the United States gave the following P/E ratios†.

(a) Use a calculator with mean and sample standard deviation keys to find the sample mean x and sample standard deviation s. (Round your answers to one decimal place.)

(b) Find a 90% confidence interval for the P/E population mean μ of all large U.S. companies. (Round your answers to one decimal place.)

(c) Find a 99% confidence interval for the P/E population mean μ of all large U.S. companies. (Round your answers to one decimal place.)
