The annualized cost of acquiring capacity for the new barracuda drives at Seagate is calculated as $25 per unit and the contibution margin for the product is $45 per unit.

a.) what service level(percentile of demand met) should seagate target for in building capacity? how much capacity will it build? the demand forcast for the barracuda drives is uniform between 100 and 200.

b.) how does this service level change, if Seagate outsources manufacturing to china, to arrive at an annualized cost of capacity of $10 per unit? How much capacity will it build?

c.) How does this service level change if the inbound shipment cost per unit from China to US reduces the margin per unit to $35? How much capacity will it build?

d.) Conduct the capacity calculations in all 3 scenarios above when the forcast for the barracuda drives is expected to follow the following distributions.

Recall the researcher who investigated the relationship between hours of sleep and reaction times in the Week 4 Application. As a follow up to that study, the researcher wants to conduct a correlation to investigate further if there is a relationship between hours of sleep and reaction time. For this experiment, participants are allowed to sleep as much as they would like (that is, they are not assigned to sleep any specific number of hours). When 20 participants come to their appointment time, they report to the researcher how many hours of sleep they had the previous night. The researcher then tests their reaction times.

(a) Define 'tests of control' and explain the importance of tests of control in the audit of a
company.

(b) You are an audit senior in Asenso Boateng & Co a firm providing audit and assurance
services. One of your clients is an exclusive hotel called 'Rock City Hotel' situated in the
centre of Airport City Accra. As part of your audit procedures you are assessing the controls
surrounding payroll. You have read last year's audit file and have obtained the following
information:
The hotel employs both full and part time staff. Due to the nature of the business most of
the work is done in shifts. All staff are paid on a monthly basis.
New members of staff are given an electronic photo identification card on the day they join
by the personnel department. This card is used to 'clock in' and 'clock out' at the start and
end of the shift to record the hours worked.
At the end of each week the information recorded on the system is sent automatically to
the payroll department and also to the head of each of the three main operating divisions:
Rooms, Food & Beverage and Corporate Events. Each division head must reply back to the
payroll department by email to authorise the hours worked by their staff.
The payroll clerk collates all the authorised information and then inputs the hours worked
into a standardised computerised payroll package. This system is password protected using
an alphanumerical password that is only known to the payroll clerk and the finance
manager.
Once the hours have been entered, the calculation of the gross pay and taxation are
calculated automatically along with any other statutory deductions. At the end of the
calculations a payroll report is produced and printed. The finance manager reviews the
report and compares the data to last month to identify and follow up any unusual variances.
When he is satisfied with the information, he authorises the payroll run by signing the
payroll report and the payroll clerk submits the data.
Payslips are sent to the home address of each employee and payment is made by bank
transfer.
Required:

With reference to the scenario:
(i) Identify and explain FOUR STRENGTHS within the hotel's internal control system in
respect of payroll.

(ii) For each of the identified strengths, state a test of control the auditor could perform to
assess if the controls are operating effectively.

Please I need help on this question

a) A manager of a firm in the area of Dukagjini region is considering to knocking down the old barn to provide much needed parking space for tractors and equipment. This project would require an immediate expense of £110,000 to remove the asbestos and to knock down the barn. Building the car park would then cost £17,000. The space created would have spare capacity, which will be rented out at £45,000 (pre-tax) per year for parking and other uses. This project also lasts five years and has no residual value at the end. The farmer is able to depreciate the total cost of removing the asbestos, knocking down the building and building the car park. This is done over the five years of the project using the straight-line method. The corporate tax rate is 28%. The nominal discount rate is 3% and all cash flows are nominal values. . At the moment the farmer is paying £3,000 per year (post-tax) to park these on a neighbour’s land.

Calculate the net present value of this project.

b) An alternative is to expand its production capacities. The only possible location is an old barn owned by the farm but not utilised because of asbestos contamination. For legal reasons the building cannot be sold or leased. At a cost of £2,000, the farmer hired an environmental expert, who produced a report with detailed plans for the removal of the asbestos in compliance with environmental regulations. To refurbish the barn—including removing the chemical substances it is expected to cost £350,000. The cheesemaking equipment costs £150,000. Starting at the end of year one, cheese production is expected to yield £170,000 yearly for five years in pre-tax revenue minus cash expenses. The firm depreciates the refurbishment cost and the cost of the cheese-making equipment over the five years of the project using the straight-line method. There is no residual value at the end of the project. The corporate tax rate is 28%. The nominal discount rate is 7% and all values are nominal values.

Calculate the net present value of this project.

c) The farmer asks for your advice on how to choose between the two projects using the information in Parts (a) and (b. What would be your advice to the farmer? Explain.

d) Why might it be appropriate to use different discount rates for different projects, such as those in Parts (a) and (b)? Briefly explain.

(The Colorable interface) Design an interface named Colorable with a void method named howToColor(). Every class of a colorable object must implement the Colorable interface. Design a class named Square that extends GeometricObjectand implements Colorable. Design another class named Trianglethat extends GeometricObjectand implements Colorable. Implement howToColor inSquareto display the message Color all four sides. ImplementhowToColor inTriangleto display the message Color all three sides.

Draw a UML diagram that involves Colorable, Square, Triangle, and GeometricObject.

In this discussion, you will apply the statistical concepts and techniques covered in this week's reading about correlation coefficient and simple linear regression. A car rental company wants to evaluate the premise that heavier cars are less fuel efficient than lighter cars. In other words, the company expects that fuel efficiency (miles per gallon) and weight of the car (often measured in thousands of pounds) are correlated. Performing this analysis will help the company optimize its business model and charge its customers appropriately.

In this discussion, you will work with a cars data set that includes two variables:

• Miles per gallon (coded as mpg in the data set)
• Weight of the car (coded as wt in the data set)

The random sample will be drawn from a CSV file. This data will be unique to you, and therefore your answers will be unique as well. Run Step 1 in the Python script to generate your unique sample data.

In your initial post, address the following items:

1. You created a scatterplot of miles per gallon against weight; check to make sure it was included in your attachment. Does the graph show any trend? If yes, is the trend what you expected? Why or why not? See Step 2 in the Python script.
2. What is the coefficient of correlation between miles per gallon and weight? What is the sign of the correlation coefficient? Does the coefficient of correlation indicate a strong correlation, weak correlation, or no correlation between the two variables? How do you know? See Step 3 in the Python script.
3. Write the simple linear regression equation for miles per gallon as the response variable and weight as the predictor variable. How might the car rental company use this model? See Step 4 in the Python script.
4. What is the slope coefficient? Is this coefficient significant at a 5% level of significance (alpha=0.05)? (Hint: Check the P-value, , for weight in the Python output.) See Step 4 in the Python script.
