Chapter 11 Homework Assignment
See your Schedule and Requirements document for the due date. Put your answer underneath each question. You may either type your answers or write them neatly and scan your document. With respect to the plots of the regression lines, you may present your answer in any reasonable way you choose (Excel, by hand, etc.). However, the regression plots must be neat and if I cannot read the writing, I cannot give credit. Submit your file(s) through the Homework Assignments link.
Lawrence Choynski, the plant controller at Bart Plastics, wants to identify cost drivers for manufacturing overhead costs. Indirect support consists of skilled staff responsible for the efficient functioning of all aspects (setup, production, maintenance, and quality control) of the plastic injection molding facility. In talking with the support staff, Choynski has the impression that the staff spends a sizable portion of its time ensuring that the equipment is set up correctly and checking that the first units of production in each batch are of good quality.
Choynski has collected the following data for the past 12 months:
Month Manufacturing
Overhead Costs Machine
Hours Number of
Batches
January $84,000 2,250 309
February 41,000 2,400 128
March 63,000 2,850 249
April 44,000 2,100 159
May 44,000 2,700 216
June 48,000 2,250 174
July 66,000 3,800 264
August 46,000 3,600 162
September 33,000 1,850 147
October 66,000 3,300 219
November 81,000 3,750 303
December 57,000 2,000 106
Total $673,000 32,850 2,436
Choynski estimates the following two regression equations:
y = $28,089 + ($10.23 x Machine-hours)
y = $16,031 + ($197.30 x Number of batches)
where y is the monthly manufacturing overhead costs.

Required:
1. Plot the monthly data and the regression lines for each of the following cost functions:
a. Manufacturing overhead costs = a + (b x Machine-hours)
b. Manufacturing overhead costs = a + (b x Number of batches)
Which cost driver for manufacturing overhead costs would you choose? Explain.
2. Choynski anticipates 2,600 machine-hours and 300 batches for next month. Using the cost driver you chose in requirement 1, what amount of manufacturing overhead costs should Choynski budget?
3. Assume the facts in requirement 2. Choynski adds 20% to costs to determine target revenues (and hence selling prices). Costs other than manufacturing overhead are expected to be $125,000 next month. Compute the target revenue numbers for next month if the cost driver for manufacturing overhead is i) machine-hours and ii) number of batches. What would happen if Choynski set target revenues and selling prices using the cost driver you did not choose in requirement 1?

Resit Coursework Submission Deadline: Tuesday 11 July 2017 at 2:00 pm
Instructions:
CW Resit : Essay choice 2 – Discuss the causes, consequences and treatment of qualitative and quantitative defects of platelets – 3,000 words maximum (no +/- 10%) with up to 8 figures/tables in total
Remember this is a level 3 Biomedical Sciences essay, so link each section, be critical and discuss the pathophysiology of disease in relation to the title.
Hints and Tips
• The essay must be fully referenced using the UWE Harvard referencing system
• Plagiarism is a serious academic offence. You must not copy and paste chunks of text from the papers you read. Instead you must write the material in your own words to show your understanding of the topic.
• For a level three essay you should be using primary sources (i.e. peer-reviewed journal articles) for most of your information
• You need to avoid using non-peer reviewed websites such as Wikipedia as references (though looking at them may give you a start point). However, you may need to use the websites of organisations such as the World Health Organisation, the Public Health England, or the Centre for Disease Control (America’s equivalent) to access up to date epidemiological data.
• The essay must be written in scientific style English – read a review article in a journal such as FEMS microbiology reviews to get a feel for what this means
• As you have plenty of time to do this essay and opportunity to “spellcheck” and proof read the essay we will expect a high standard of editorial quality – for example bacterial names must be spelt correctly and typed in italics; gene names must also be in italics however protein names should be in standard print.
• Make sure you set your “spellcheck” dictionary to UK English
• Avoid the use of single sentence paragraphs
• Use tables, graphs and images where they add to your account
• You need to be critical of the literature, if two papers disagree with each other you will need to try to discuss why they disagree
• This question requires that you state an opinion, so make sure the essay content and your conclusion match
