Overview: Advances in technology have impacted many facets of the auditing process, from assessing risk and internal control to conducting substantive procedures. These changes both create challenges and offer opportunities for auditing professionals. Prompt: For this short paper, you will use the internet to research the impact of a specific technology on auditing. You will provide a description of the technology, an explanation of its current and potential future impact on auditing, and a suggestion of how auditing and auditors can better adapt to the changes brought about by the technology. Use the resources provided in this module for help choosing and researching a topic. Specifically, the following critical elements must be addressed:  Technology Description: Provide a brief description of the technology you chose.  Impact on Auditing: Provide an explanation of the current impact of the technology on auditing and its potential future impact. Support your analysis with research.  Suggestions for Adapting: Provide suggestions for how auditors can better adapt to the changes brought about by the technology. If the technology you chose creates challenges for the profession, make suggestions for how auditors can adapt to meet these challenges. If the technology offers opportunities for the profession, make suggestions on how auditors can better adapt to take advantage of these opportunities. Support your suggestions with research.

Assignment:

  • Use RStudio to generate a word document with basic data analysis of the following dataset: dataset_price_personal_computers.csv  

Questions/Requests:

  • Create a summary of stats for the dataset. (provide a screen shot)
  • Create a correlation of stats for the dataset. (provide a screen shot) (Hint: Transform may be needed)

We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different “digits” {0,1,…,9}.{0,1,…,9}. Sometimes though it is useful to write numbers hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0,1,…,9,A,B,C,D,E,F}.{0,1,…,9,A,B,C,D,E,F}. So for example, a 3 digit hexadecimal number might be 2B8.

How many 3-digit hexadecimals are there in which the first digit is E or F?

How many 4-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)?

How many 4-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)?

In a recent survey, 43 students reported whether they liked their potatoes Mashed, French-fried, or Twice-baked. 24 liked them mashed, 23 liked French fries, and 12 liked twice baked potatoes. Additionally, 11 students liked both mashed and fried potatoes, 9 liked French fries and twice baked potatoes, 10 liked mashed and baked, and 2 liked all three styles. How many students hate potatoes? Explain why your answer is correct.

How many positive integers less than 975 are multiples of 8, 7, or 9? Use the Principle of Inclusion/Exclusion.

We want to build 5 letter “words” using only the first n=12n=12 letters of the alphabet. For example, if n=5n=5 we can use the first 5 letters, {a,b,c,d,e}{a,b,c,d,e} (Recall, words are just strings of letters, not necessarily actual English words.)

  1. How many of these words are there total?
  2. How many of these words contain no repeated letters?
  3. How many of these words start with the sub-word “ade”?
  4. How many of these words either start with “ade” or end with “be” or both?
  5. How many of the words containing no repeats also do not contain the sub-word “bed”?

Energyshot is a new energy drink that is about to be introduced into the global market. You are the executive in charge of marketing it in some of the lesser developed countries such as Honduras and Haiti. You are aware that food and milk in these countries is more expensive than Energyshot. Your boss thinks that one television advertisement campaign should be sufficient for all markets, just changing the translation to suit the language differences.

  • Discuss what effect an advertising campaign touting how “the boost of energy from Energyshot will last the whole day!” will impact these lesser developed countries.
  • What are the ethical and social responsibility ramifications of a populace too poor to afford much food using this drink instead?
  • What would you do as the marketing manager for this drink for these countries?

An electron is accelerated inside a parallel plate capacitor. The electron leaves the negative plate with a negligible initial velocity and then after the acceleration it hits the positive plate with a final velocity β. The distance between the plates is 11.0 cm, and the voltage difference is 147 kV. Determine the final velocity β of the electron using classical mechanics. (The rest mass of the electron is 9.11×10-31 kg, the rest energy of the electron is 511 keV.)

What is the final velocity β of the electron if you use relativistic mechanics?

There is a region with a constant magnetic field 6.31T . The magnetic field is directed out of the page. A conducting rod moves with a velocity of 1.58m/s , along a V shaped wire that is in the shape of a right triangle. At time = 0 s the rod is at the vertex of the triangle where the angle at the vertex is 19degrees . The right angle is where the conducting rod is. This means the rod is moving along the x axis and the rod is the y axis.

What is the emf induced in the rod after it has moved from the vertex for a time of 10.9s ?

emf = V

What is the current induced in the rod if the resistance is 5.31ohms ?

i = A

What is the power in the rod?

A 42-year-old man presents with an 8-hour history of testicular pain, which is increasing in

severity. He is in acute distress by the time you see him and complains of groin pain. He

notes some urinary frequency and nausea. His physical ex is unremarkable with

normal testicular and scrotal ex and mild left costovertebral angle tenderness.

Urinalysis reveals significant microscopic hematuria.

Questions:

1. Will you treat and/or refer? What follow-up is needed?

2. What education is needed for this patient for the future?

3. Are there any complementary therapies to assist this patient in control of his underlying condition long range? Support with evidence from the literature.
