Sophia who took the Graduate Record Examination (GRE) scored 167 on the Verbal Reasoning section and 161 on the Quantitative Reasoning section. The mean score for Verbal Reasoning section for all test takers was 155 with a standard deviation of 7.06, and the mean score for the Quantitative Reasoning was 151 with a standard deviation of 7.11. Suppose that both distributions are nearly normal.

Extensions of Demand and Supply Analysis

1. Graph the accompanying demand data, and then use the midpoint formula for Ed to determine price elasticity of demand for each of the four possible $1 price changes. What can you conclude about the relationship between the slope of a curve and its elasticity? Explain in a
   nontechnical way why demand is elastic in the northwest segment of the demand curve and inelastic in the southeast segment.

2- Calculate total-revenue data from the demand schedule in question 2. Graph total revenue below your demand curve. Generalize about the relationship between price elasticity and total revenue.

Exercise 4–Timing Sorting AlgorithmCollect the run times for either selection sort or insertion sort (use random values for an array and sorted values; sorted the same list twice and collect time each time) for the following array sizes: 1000, 2000, and 10000. You should be able to confirm that the runtime is n^2 for unsorted list (i.e., going from 1000 to 2000 should be about 4 times slower and going from 1000 to 10000 should be about 100times slower).

Question 1: Does your sorting algorithm in exercise4run faster for a sorted listthan an unsorted list?Explain why or why not.

Question 2: What are some reasons for doing algorithm analysis and expressing running time in O notation?

Answer the following questions:

a) List Zappos’ 10 Core Values.

b) Now, pretend you are the HR manager at Zappos and you are preparing to

interview an applicant for a customer service position at Zappos. The position

requires this person to answer customer questions about its products, over the

phone.

Select 3 core values and write 2 interview questions for each of the 3 core values

(Yes, you will be writing a total of 6 interview questions).

C. Be sure to explain why you are using the interview question and what you hope it

will reveal about the applicant. You are not allowed to use one of the interview

questions presented in the video or in the attached document. Come up with your

own interview questions. Be creative!

Your task is to develop quantified Risk models of two Risks of interest to you. This is an academic
exercise and its purpose is to make you familiar with the process of quantified Risk modelling and
to show me you understand the theory and the practice.
a) Write up each Risk as a case study that explains the Risk in detail and describes the proposed
control measures.
b) Estimate/judge the values that could realistically be given to the various parameters relevant to
modelling Risk and explain your reasoning to me. Don’t spend inordinate amounts of time
trying to justify any of the values that have to be estimated/judged in order to complete the task
(eg. does a death cost $3M or is it $3.2M? Is the Exposure 20 times a year or 18?). However,
ensure that you do have justification for the values you use as I am not interested in you simply
using a number with no justification.
c) Use your spreadsheet to estimate the position of the Risk line, using any necessary “reality
checks”. In other words, justify or even make a clear statement of the inadequacies of what
you have done and the need for further investigation. Estimate the Risk value.
d) Propose a possible control measure change/improvement and estimate the associated
implications for productivity, recurrent costs and/or capital requirements. I am well aware
these may based on judgement unless you have a close knowledge of a particular case.
e) Provide me with an explanation of the anticipated effect of this proposed control measure on
each of the parameters that determine Risk and use this to justify a reduction in the Risk value
estimated before this improved control measure is applied.
f) Use this to estimate the effect of the improved control measure on one or both (as appropriate)
of recurrent costs and payback period.

2 page paper describing the following

Provide a description of an organization you are familiar with (possibly a company you have worked for in the past or are currently working for) and describe briefly what services they contribute. Then, select three out of the six questions below

and provide detailed answers, supporting those answers by referencing any sources used. Be sure to use examples from your research to strengthen your argument as needed

·What personal knowledge management tools does this organization utilize?

·What steps has this organization taken in securing their information and knowledge?

·What has this organization done to gain and sustain an advantage over their competitors?

·Describe in detail how this organization manages the components of its IT infrastructure

In what ways does the organization demonstrate successful collaboration?

·Identify at least two types of hardware and two types of software used by this organization.

Singing Fish Fine Foods has $1,910,000 for capital investments this year and is considering two potential projects for the funds. Project 1 is updating the​ store's deli section for additional food service. The estimated​ after-tax cash flow of this project is $610,000 per year for the next five years. Project 2 is updating the​ store's wine section. The estimated annual​ after-tax cash flow for this project is $530,000 for the next six years. If the appropriate discount rate for the deli expansion is 9.7% and the appropriate discount rate for the wine section is 9.1​%, use the NPV to determine which project Singing Fish should choose for the store. Adjust the NPV for unequal lives with the equivalent annual annuity. Does the decision​ change? If the appropriate discount rate for the deli expansion is 9.7​%, what is the NPV of the deli​ expansion? If the appropriate discount rate for the deli expansion is 9.1%, what is the NPV of the deli​ expansion?
