2020 Election ~ Bernie Sanders is a popular presidential candidate among university students for the 2020 presidential election. Leading into Michigan’s presidential primary election in 2020, a journalist, Lauren took a random sample of 11,590 university students and found that 8,066 of them support Bernie Sanders.

Using this data, Lauren wants to estimate the actual proportion of university students who support Bernie Sanders.

To calculate the required sample size, what value ofz*. should we use in the formula below to calculate a 90% confidence interval within 2.82 percentage points? Give your answer to 4 decimal places.

n=p*(1−p*)(z*ME)2

This semester, there are 259 professors at University A and 128 sent in midterm progress reports. Again, assume the professors at University A are representative of all professors.

(a) Construct a 95% confidence interval for the proportion of all professors who sent in midterm progress reports this semester, and then interpret it. Note: Remember that a confidence interval is made up of three components: pˆ, z, and n. You should have all the information you need to construct the interval.

(b) At CSU San Bernardino, they have 176 professors, of whom 74 sent in midterm progress reports for their students. Is the 95% confidence interval for CSU San Bernardino wider or smaller than the one for University A? Explain answer.

1. Based on Chapter 10: Making Capital Investment Decisions:

Conch Republic Electronics is a midsized electronics manufacturer located in Key West, Florida. The company president is Shelley Couts, who inherited the company. When it was founded over 70 years ago, the company originally repaired radios and other household appliances. Over the years, the company expanded into manufacturing and is now a reputable manufacturer of various electronic items. Jay McCanless, a recent MBA graduate, has been hired by the company’s finance

department.

One of the major revenue-producing items manufactured by Conch Republic is a smartphone. Conch Republic currently has one smartphone model on the market, and sales have been excellent. The smartphone is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffett music. However, as with any electronic item, technology changes rapidly, and the current smartphone has limited features in comparison with newer models. Conch Republic spent $750,000 to develop a prototype for a new smartphone that has all the features of the existing smartphone but adds new features such as WiFi tethering. The company has spent a further $200,000 for a marketing study to determine the

expected sales figures for the new smartphone.

Conch Republic can manufacture the new smartphones for $220 each in variable costs. Fixed costs for the operation are estimated to run $6.4 million per year. The estimated sales volume is 155,000, 165,000, 125,000, 95,000, and 75,000 per year for the next five years, respectively. The unit price of the new smartphone will be $535. The necessary equipment can be purchased for $43.5 million and will be depreciated on a seven-year MACRS schedule. It is believed the value of the

equipment in five years will be $6.5 million.

As previously stated, Conch Republic currently manufactures a smartphone. Production of the existing model is expected to be terminated in two years. If Conch Republic does not introduce the new smartphone, sales will be 95,000 units and

Page 1 of 2

65,000 units for the next two years, respectively. The price of the existing smartphone is $385 per unit, with variable costs of $145 each and fixed costs of $4.3 million per year. If Conch Republic does introduce the new smartphone, sales of the existing smartphone will fall by 30,000 units per year, and the price of the existing units will have to be lowered to $215 each. Net working capital for the smartphones will be 20 percent of sales and will occur with the timing of the cash flows for the year; for example, there is no initial outlay for NWC, but changes in NWC will firstoccur in Year 1 with the first year’s sales. Conch Republic has a 21 percent corporate

tax rate and a required return of 12 percent.

Shelley has asked Jay to prepare a report that answers the following questions.

1. What is the payback period of the project?

2. What is the profitability index of the project?

3. What is the IRR of the project?

4. What is the NPV of the project?

XYZ Electronics is a mid-sized electronics manufacturer located in Germany. The company president is Mark Johnson, who inherited the company. When it was founded, over 70 years ago, the company originally repaired radios and other household appliances. Over the years the company expanded into manufacturing, and is now a reputable manufacturer of various electronic items. Sam Smith, a recent MBA graduate, has been hired by the company’s finance department.

One of the major revenue-producing items manufactured by XYZ is a personal digital assistant (PDA). XYZ currently has one PDA model on the market, and sales have been excellent. The PDA is a unique item in that it comes in a variety of tropical colours and is pre-programmed to play Billy Bragg music. However, as with any electronic item, technology changes rapidly, and the current PDA has limited features in comparison with newer models. XYZ spent €750,000 to develop a prototype for a new PDA that has all the features of the existing PDA but adds new features such as cell-phone capability. The company has spent a further €200,000 for a marketing study to determine the expected sales figures for the new PDA.

XYZ can manufacture the new PDA for €155 each in variable costs. Fixed costs for the operation are estimated to be €4.7 million per year. The estimated sales volumes are 74,000, 95,000, 125,000, 105,000 and 80,000 per year for the next five years, respectively. The unit price of the new PDA will be €360. The necessary equipment can be purchased for €21.5 million, and will be depreciated using the 20 per cent reducing-balance method. It is believed the value of the equipment in five years will be €4.1 million.

As previously stated, XYZ currently manufactures a PDA. Production of the existing model is expected to be terminated in two years. If XYZ does not introduce the new PDA, sales will be 80,000 units and 60,000 units for the next two years, respectively. The price of the existing PDA is €290 per unit, with variable costs of €120 each and fixed costs of €1,800,000 per year. If XYZ does introduce the new PDA, sales of the existing PDA will fall by 15,000 units per year, and the price of the existing units will have to be lowered to €255 each.
