PC.52 At the start of the semester Custom Kicks personnel were
struggling to quickly customize their shoe inserts to their
customers' feet. This hurt sales as customers became frustrated
during the customization process and would hesitate to refer
friends.
During week three of running the business, it took an average
employee about 25 minutes to customize one pair of inserts.
Recognizing this challenge, management and key employees analyzed
the customization process and made some time-saving changes. Two
weeks later, after training all employees on the new process, an
average employee could customize a pair of inserts in about 18
minutes.
In this case, what is the output that should be
used for productivity calculations?
|
1 pair (of customized inserts) |
||
|
18 minutes |
||
|
25 minutes |
After making the time-saving changes mentioned above, how many pair
of inserts could an average employee complete in one hour? (Display
your answer to two decimal places.)
After making the time-saving changes mentioned above, by what
percentage did Custom Kicks' productivity increase? (Write your
answer as a percentage, and display your answer to
two decimal places.)

Case Study Charlie is a 3-year-old at a community preschool facility. The staff reported he tends to put everything in his mouth and is frequently found eating dirt. A home visit by a school staff member to discuss the problems with his parents revealed a generally clean environment in a very old home that was being renovated. Recently Charlie has been falling well behind in academic skills compared to other children in his class; his linear growth has slowed, and he is tired and irritable. His physician noted pallor and what look like “pencil lines” on the gums adjacent to the teeth. He ordered blood tests that revealed a low hemoglobin level and an elevated lead level. Discussion Questions Based on the patient history, the signs/symptoms, and lab test results, discuss the probable environmental factors responsible for Charlie’s ingestion of lead. (See: Heavy Metals—Lead) Discuss the other toxic effects of lead poisoning that Charlie may experience if the situation is not addressed. Discuss other possible sources in children’s environments that have been identified as containing lead.

a) Construct a 4x2 contingency table that illustrates the relationship between the following two variables: Hospital at which the patient was seen, and whether or not the patient had LDL £ 100 mg/dl. Use the Hospital names as the row headings and whether or not the patient had LDL £ 100 mg/dl as the column headings. Include the overall total as well as row and column totals. Use your table to answer the questions in parts b – e. (Note: Be careful when filling in your table - not all patients have data for these variables. When answering the questions below, use totals from your table.)
b) What percentage of all patients had LDL > 100 mg/dl?
c) What percentage of the patients at VAMC Brooklyn had LDL > 100 mg/dl?
d) What percentage of the patients at VAMC Detroit had LDL > 100 mg/dl?
e) What percentage of the patients having LDL £ 100 were seen at SUNY Brooklyn?

You are a recent accounting graduate and have been employed in the Financial Reporting Unit of Myer Holdings Ltd, an ASX listed firm. Preparations are underway for the completion of the general purpose financial report for the year ended 29 July 2018 and you have been asked by the Chief Financial Officer to identify any major accounting issues which will need to be considered. Your attention is drawn to a media release by ASIC on 31 May 2018 (ASIC Media Release 17‐162) and this identifies areas of concern where attention will be directed in the ASIC surveillance program. Not surprisingly given a recent academic paper1 ‘impairment of assets’ receives specific mention.
Required:
You are required to prepare a report for the CFO considering whether impairment of assets is an issue requiring address for the firm.
The report should, with reference to AASB 136:
a) With reference to Myer outline what evidence is there that impairment testing of assets is necessary;
b) With reference to Myer outline the processes required to be addressed in determining any asset impairments that might be necessary

Students in a representative sample of 65 first-year students selected from a large university in England participated in a study of academic procrastination. Each student in the sample completed the Tuckman Procrastination Scale, which measures procrastination tendencies. Scores on this scale can range from 16 to 64, with scores over 40 indicating higher levels of procrastination. For the 65 first-year students in this study, the mean score on the procrastination scale was 36.9 and the standard deviation was 6.46. (a) Construct a 95% confidence interval estimate of μ, the mean procrastination scale for first-year students at this college. (Round your answers to three decimal places.) , (b) Based on your interval, is 40 a plausible value for the population mean score? Yes No What does this imply about the population of first-year students? This implies that students at this university never have high levels of procrastination. This implies that on average, students at this university do not have high levels of procrastination. This implies that students at this university sometimes have high levels of procrastination. This implies that on average, students at this university do have high levels of procrastination. This implies that students at this university always have high levels of procrastination.

Let's take a moment to make some connections in the material we have been exploring for the last several weeks.
First, examine the decision-making model introduced on page 148 of our textbook. As mentioned in our textbook, this model reflects the "five steps necessary to make an informed and desirable decision" (Sukiennik & Raufman, 2016,p. 148). The first step is to define a goal.
Return to this discussion to share one clearly defined personal goal along with specific objectives to help you achieve it, as illustrated on page 152 of the textbook. As you work on your goal, review the decision-making styles on page 144 of the textbook and discuss if you anticipate any of these to impede your progress.
Are you not sure where to start? Perhaps you want to address a time or stress management challenge identified earlier in the course that you have not yet overcome, or you can work on how you manage your financial resources as discussed on pages 154-157.
To wrap up your discussion post, how is the goal you define for yourself going to help your academic or professional success?

Allisson Russo is a 15 year old girl admitted to the
Emergency Room with Right , lower quadrant pain. She is eventually
diagnosed with appendicitis and scheduled for an appendectomy.
After visiting Allison in the Er, the surgeon Alerts the Operating
Room nurse, Ms. Wendy Harnes that the surgery will take place in an
hour. Allison is HIV positive from emergency medical acre and blood
transfusions that she received six years ago, following an auto
accident. Allison does not know that she is positive, at the
request of her parents, who are born high-powered attorneys.
Allison tells Ms. Harnes that she used to to be involved in sports
but has dropped these activities in school because of feeling more
tired than usual. She thinks that her academic studies are simply
requiring more of her attention , but her mother has suggested that
perhaps she would be seeing a new doctor soon. Allison asks the
nurse “ Do you think being tired at my age is a serious concern? I
thought all teenagers feel like this. I feel that I have a serious
health problem.” How should Ms. Hayes respond to Allison?

1. What are the elements of team leadership?
2. Ethics is the study of morally right behaviors and
character.
i. The manufacturing cost of the widgets your company makes has
dropped by 50%. One of your customers, Sam, tells you he knows this
because he is best friends with your company’s Vice President of
production and asks you for a discount on his order. Your boss
accepts this request. Your other customer, Sue (who is one of your
best friends and knows nothing about the drop in manufacturing
costs), places the exact same order for widgets as Sam. Do you
offer her a similar discount? Do you tell her about the drop in
manufacturing costs?
ii. You are a working student, a manager of a company. Your company
has engaged you for a whole month, so you have not had enough time
to focus on completing and submitting your assignment. You have 48
hours to submit a 3,000 words assignment. Your classmate has
offered to do your assignment for you, but your religious values
does not permit you to allow this academic misconduct. What will
you do?
