A developer wants to know if the houses in two different neighborhoods were built at roughly the same time. She takes a random sample of six houses from each neighborhood and finds their ages from local records. The accompanying table shows the data for each sample​ (in years). Assume that the data come from a distribution that is Normally distributed. Complete parts a through c below.

​a) Find a 95% confidence interval for the mean​ difference, μ1−μ2​, in ages of houses in the two neighborhoods

b) Is 0 within the confidence interval

c) What does the confidence interval suggest about the null hypothesis that the mean difference is 0?

Even, in 1921, the Dodge Brothers built a boat named the SS Delphine and it had a whopping 3000 HP. 

So, how much horsepower would a Challenger SRT® Hellcat Redeye Widebody need to tow the SS Delphine up the industry standard: Davis Dam Grade Climb?


Pro Tips

Davis Dam assumed grade = 7%


Air density is sea level conditions (.002377 slugs/f^t3)


w(weight) of the SS Delphine + trailer + Redeye = 3,922,000 + 150,000 + 4451 Lbs


Crr = coefficient of rolling resistance = .015


Assume Combined CDA is 1555 ft^2


SAE J2807 (Davis Dam Grande Climb) - min speed is 40mpg (59 ft/s)


F(drag) = 1/2p x V^2 x C(d)A


F(rolling resistance) = W x cos x Crr


F(weight) = W x sin


F(sum) = F(drag) + F(rr) + F(weight)


P = F(sum)XV


convert to horsepower = P(1hp/550ft lbf/sec)

A circular circuit of radius 30 cm is built to rotate about a

pair of insulating posts. The circuit consists of a 100 volt

battery, two 25 kW resistors in parallel and one 75 kW

resistor in series. The circuit is exposed to an external uniform magnetic field

of magnitude 0.75 Tesla and directed 20 degrees from the

normal vector of the circuit and the axis of rotation.

Calculate the total torque (magnitude and direction) on the

circuit

Calculate the component of the torque on the circuit

(magnitude and direction) at point A (exactly ¼ of the way

around the loop)

Calculate the component of the torque on the circuit

(magnitude and direction) at point B (exactly 7/8 of the way

1. A fund is built with annual deposits increasing by 1 from 1 to 10 and then decreasing by 1 to $0 at an annual effective interest rate of 5%. At the end of 19 years, the fund is used to purchase a 8-year annuity with level payment $X at an annual effective interest rate of 3% with the first payment 20 years from today.

Calculate X

2. Annie wants to accumulate $60500 in a fund at the end of 20 years. She plans to deposit $800+tX at the end of year t (t = 1,2,...,10) and $1500 at the end of last 10 years. The fund earns an annual effective interest rate of 6%.

Calculate X

  1. The built-in data “trees” provide the measurements of diameter (Girth), height and volume of trees. These are in inches for Girth, feet for Height and cubic feet for Volume. We will focus on Girth and Height. Write a function convert() that converts the values into the metric system (meters). Your function should take as arguments the value to convert and the unit it was expressed in (inches or feet) (use the following: x inches = x*0.0254 meters, x feet = x*0.3048 meters). If the first argument is not numeric or if the second argument is not “inch” or “feet”, use stop() function with an error message. Here is how it should work:

> convert(8.3,"inches")

[1] 0.21082

> convert(8.3,"feet")

[1] 2.52984

> convert(8.3,"foot")

Error in convert(8.3, "foot") : the unit was not "inches" or "feet"

Use your function to convert the values of Girth and Height to meters. Using cor.test() function, calculate the correlation (and the corresponding p-value) between Girth and Height in meters.

  1. The Coase theorem is built on certain assumptions that, if violated, implies that private bargaining may not always achieve an efficient outcome. Give two cases where we cannot expect private bargaining to deliver an efficient outcome, where each case represents a violation of a different underlying assumption. Briefly explain your answers.

Mark Burnett and Kamran Pourgol were the only shareholders in a corporation that built and sold a house. When the buyers discovered that the house exceeded the amount of square footage allowed by the building permit, Pourgol agreed to renovate the house to conform to the permit. No work was done, however, and Burnett filed a suit against Pourgol. Burnett claimed that, without his knowledge, Pourgol had submitted incorrect plans to obtain the building permit, misrepresented the extent of the renovation, and failed to fix the house. Was Pourgol guilty of misconduct? If so, how might it have been avoided? Discuss.

1) Burnett is a (memeber, partner, or shareholder) in the corporation.

2) Pourgol held a (majority, minority, unclear) amount of shares in the close corporation.

3) Assume that Pourgol and Burnett agreed to the plans submitted to the town and Burnett and was made aware beforehand of the promise to fix the buyer's home. Would Pourgol most likely be held liable in this instance? (yes, no)

4) Would the buyers still be able to recover the costs of renovation to conform the house allowed by the building permit? (yes, no)

Firm XYZ is considering a project to built a new facility to install a new production line. The firm requires a minimum return of 10% in this project, due to the risks involved. The firm is a 34% tax bracket. Sales, revenues and costs details are given in the table below:

Cost of new plant and equipment

$9,700,000

Shipping and installations costs

$300,000

Unit Sales forecasted

                                             Year 1 50,000

          Year 2 100,000

          Year 3 100,000

        Year 4 70,000

        Year 5 50,000

Sales price per unit sold

$145

Variable costs per unit produced

$80

Annual fixed costs

$500,000

Net Working Capital requirements

An initial $100,000 will be needed to start production. After that, net working capital requirements until year 5 will be equal to 5% of the total sales for the year. No NWC will be recuperated at the end of year 5

Depreciation

Using the straight-line method, the depreciation expense is $2,000,000 per year during the five years of the project life.

Tasks:

Estimate the CCFA for the next 5 years of operation

Using the NPV and IRR decision methods, decide if the firm should take the project.
