In constructing 95% confidence interval estimate for the difference between the means of two populations, where the unknown population variances are assumed not to be equal, summary statistics computed from two independent samples are: ?1=45,?̅1=756,?1=18,?2=40,?̅2=762,?2=15

(using 2-sample T menu)

a. Calculate the 95% confidence interval for the true difference of two means.

b. Base on the interval in the previous question, can one conclude there is a difference in means of two populations?

Justify your answer.

Voltage and Insulating Fluid. Researchers examined the time in minutes before an insulating fluid lost its insulating property. The following data are the breakdown times for eight samples of the fluid, which had been randomly allocated to receive one of two voltages of electricity:

Times (min) at 26 kV: 5.79 1579.52 2323.70
Times (min) at 28 kV: 68.8 108.29 110.29 426.07 1067.60

(Please explain/list every step in details)

1. Form two new variables by taking the logarithms of the breakdown times: Y1 = log breakdown time at 26 kV and Y2 = log breakdown time at 28 kV.

2. By hand, compute a 95% confidence interval for the difference in mean log breakdown times. Take the antilogarithms of the endpoints and express the result in a sentence.

Part 1 Write a program that displays a frame containing two labels that display your name, one for your first name and one for your last. Experiment with the size of the window to see the labels change their orientation to each other. USE FIRST NAME: Aya LAST NAME: KAYED. SEND THE CODE IN THE EXACT FORMAT FOR JAVA ECLIPSE. I WILL COPY AND PASTE THE CODE SO I CAN RUN IT. Part 2 Propose and solve your own digital design problem.

Case Analysis 3: You are the General Manager at the Bicker, Slaughter, and Lynch Law Firm. There is an opportunity to buy out a small law firm that was just started by a young MBA/JD, and you believe the firm can be grown and become a lucrative part of your Firm. With help from your finance leader, you have estimated the following benefit streams for this new division:

Before Tax Cash Flow From Operations

Year 1 $(149,000)

Year 2 $0

Year 3 $51,380

Year 4 $88,760

Year 5 $114,100

Year 6 $129,780

Year 7 $143,640

Year 8 $167,300

After Tax Net Income From Operations

Year 1 $(103,500)

Year 2 $(50,500)

Year 3 $36,700

Year 4 $63,400

Year 5 $81,500

Year 6 $92,700

Year 7 $102,600

Year 8 $119,500

After Tax Cash Flow From Operations

Year 1 $(85,600)

Year 2 $15,000

Year 3 $48,600

Year 4 $72,200

Year 5 $95,550

Year 6 $101,300

Year 7 $125,200

Year 8 $140,200

You estimate that the purchase price for this firm would be $200,000 and that additional net working capital would be needed in the amount of $60,000 in year 0, an additional $15,000 in year 2 and then $15,000 in year 5.

• BSL usually spend about $275,000 per year in advertising. If you make this acquisition, you would ask that advertising spending be increased by an incremental one-time amount of $45,000 in year 0 to publicize the firm’s expansion.

• Your finance leader has indicated that the firm has access to a credit line and could borrow the funds at a rate of 6%. He also mentions that when he runs project economics for capital budgeting (such as a new copier or a company car), he recommends a standard 10% rate discount, but the one other time they looked at an acquisition of a smaller firm, he used a 13% rate discount. Obviously you will want to select the most appropriate discount rate for this type of project.

• At the end of 8 years, the plan is to sell this division. The estimated terminal value (the sale and the return of working capital) is conservatively estimated to be $350,000 of after-tax cash flow help.

Using the data that you need (and ignoring the extraneous information), for this potential acquisition, calculate each of the following items: the Nominal Payback, the Discounted Payback, the Net Present Value, the IRR.

In an MS Word document, in paragraph form, respond to the following questions:

1) From a purely financial (numbers) perspective, would you recommend this purchase to management? Why?

2) What are some of the non-financial elements that need to be considered for this proposal?

3) Assumptions in project economics can have a huge impact on the result. Identify 3 financial elements/assumptions in your analysis that would make this project financially unattractive? In other words, what would have to be true for this to be a bad investment?

4) If you were the CEO, would you approve this proposal? Why or why not?

The company is considering a project involving the purchase of new equipment. Change the data area of your worksheet to match the following: Use Exhibit 7B-1 and Exhibit 7B-2. (Use appropriate factor(s) from the tables provided.)

a. What is the net present value of the project? (Negative amount should be indicated by a minus sign. Round your present value factor to 3 decimals and round all other intermediate calculations to nearest whole dollar.)

c. The internal rate of return is between what two whole discount rates (e.g., between 10% and 11%, between 11% and 12%, between 12% and 13%, between 13% and 14%, etc.)?

d. Reset the discount rate to 12%. Suppose the salvage value is uncertain. How large would the salvage value have to be to result in a positive net present value?

Write a program using a Scanner that asks the user for a number n between 1 and 9 (inclusive). The program prints a triangle with 2n - 1 rows. The first row contains only the square of 1, and it is right-justified. The second row contains the square of 2 followed by the square of 1, and is right justified. Subsequent rows include the squares of 3, 2, and 1, and then 4, 3, 2 and 1, and so forth until n rows are printed. Starting at row n + 1, the squares between (n - 1) to 1 are printed, again right justified.  Row n + 2 prints the squares between (n -2) to 1.

Assuming the user enters 4, the program prints the following triangle of 7 rows to the console

              1
          4  1
      9  4  1
16  9  4  1
      9  4  1
          4  1
              1

If the user enters 7, the following 13-row triangle is printed

                              1
                          4  1
                      9  4  1 
                16  9  4  1
           25 16  9  4  1
      36 25 16  9  4  1
 49 36 25 16  9  4  1
      36 25 16  9  4  1
           25 16  9  4  1
                16  9  4  1 
                      9  4  1
                          4  1
                              1

Notes

• Your solution should NOT use the conditionaloperator
• Your solution should NOT use tabs
• Your solutions SHOULD have at least one nested loop

Hint

Don't think of the output as a triangle. Think of it as two rectangular tables: one of the first n rows, the second of the last (n-1) rows.

Within each table, some cells are three spaces, some are one space and two digits, and some are two spaces and one digit.

Start by printing an entire table with each cell its appropriate square value. Then figure out how to replace the cells that should "empty" with three spaces instead of a number.

Finally, figure out how to print the one-digit numbers as two spaces and one digit, and the two-digit numbers as one space and two digits.
