3 dimensions of risk management 
Potential risks during a server       database migration 
Request for proposal for new web       servers 

Imagine you’ve been asked by the CIO of the organization you chose to create¯a Microsoft® PowerPoint®¯presentation, along with an accompanying summary guide handout, for the managers of the IT, accounting/finance, and engineering departments to inform them of the 3 dimensions of risk management (risk identification, risk assessment, and risk mitigation). 
The 3 dimensions of risk management shape the organizational framework of project risk management and determine the degree of freedom used to classify various realizations of uncertainties, resulting in a formalized systematic analysis of physical systems. 
Research information about the organization you chose to complete this week’s assignment. 
Part A: 
Create a 4- to 6-slide, media-rich Microsoft PowerPoint¯presentation that describes each of the 3 dimensions, including their definitions, values, and importance to your company. Identify the potential security risks to an organization in each of the following outsourcing situations: 

The implementation of an external       service provider for data/security protection 
The use of contractual service       providers for processing information systems applications such as a       payroll, human resources, or sales order taking 
The use of an offshore company to       support your desktop computers 
The use of¯a¯third-party governance       program to provide network support 

Note:¯Include multimedia such as graphics, pictures, video clips, or audio in a¯media-rich presentation. 
Part B: 
Create a 1-page Microsoft¯Word Summary Guide on your presentation. 
Include the following: 

Discuss risk considerations during the       development and implementation of information systems 
Discuss the importance of information       systems risk management 
Summarize the organizational risk       management framework 
Include the risk register of the       highest risk of information security to the organization 

Include APA-formatted citations to support your assignment.

By Day 3
Using SPSS:

Take a random sample of 100.
Calculate the 95% confidence interval for the variable.
Calculate a 90% confidence interval.
Take another random sample of 400.
Calculate the 95% confidence interval for the variable.
Calculate a 90% confidence interval.

Post your results, the mean of Age to verify the dataset you used, and an explanation of how different levels of confidence and sample size affect the width of the confidence interval. Next, consider the statement, Confidence intervals are underutilized and explain what the implications might be of using or not using confidence intervals. Provide examples based on the results of your data. Also, use your research to support your findings.

For this Assignment:
Write a 2- to 3-paragraph analysis of your results and include a copy and paste of the appropriate visual display of the data into your document. If you are using the Afrobarometer Dataset, report the mean of Q1 (Age). If you are using the HS Long Survey Dataset, report the mean of X1SES.
Based on the results of your data in this confidence interval Assignment, provide a brief explanation of what the implications for social change might be.

Intro to Probability – Homework Assignment 1

Please solve the problems and type the solutions up using LateX and the template provided. Naming instructions for the file you will submit are contained in the file itself. Please justify your answers and don’t simply give the answer.

Problem 1 How many plate numbers can be created in California format DLLLDDD, where D stands for digit and L stands for letter? What if no repetitions are allowed in the digits?

Problem 2 A zip code consists of 5 digits. If the first cannot be the digit 0, how many zip codes can be generated?

Problem 3 How many letter arrangements can be made from the letters of the word Iowa? How about from the letters of Connecticut?

Problem 4 How many 5-card poker hands are there? (A regular deck has 52 cards).

Problem 5 Assuming that you can only move to the right or down, in how many ways can you get from the top left point to the bottom right one along the depicted grid?

Problem 6 If you need to split a class of 32 students in 8 groups of 4, in how many ways can you do it?

Problem 7 If a student is required to solve 8 out of 10 assigned problems, how many choices does she have? What if the first 4 problems are mandatory?

Problem 8 How many actual digit numbers exist? What if no two consecutive digits can be the same? How many numbers with at most digits exist? Numbers are to be understood as actuall numbers: 1 is a one digit number but 001 is not an actual number and certainly not a 3 digit number.

Problem 9 A total of 6 people need to be selected from a set of 10 twins of different families (20 people total). How many choices are there, if it is not allowed to select two siblings?

Problem 10 A total of 8 representatives need to be chosen from a group of 40 students, of which 24 are female and 16 are male. In how many ways can this be done? What if we require that there be at least 3 female and 3 male representatives?

In many applications, some variables evolve over time in a random (stochastic) way in that even if you know

everything up to time t, it is still impossible to know for sure which values the variables take in the future.

Stochastic processes are mathematical models that describe these phenomena when the randomness is driven

by something out of the control of the relevant decision makers. For example, the stock prices can be (and

usually are) modeled as stochastic processes, since it is difficult for an investor to affect them. However, in a

chess game, the uncertainty in your opponents’ future moves are not modeled as stochastic processes as they

are made by a decision maker with the goal to defeat you and they may be adjusted based on your moves.

One simple and widely used class of stochastic processes are Markov chains. In this question, we study

Markov chains on a finite state space. There is a sequence of random variables x0, x1, …, xt, …, each taking

value in a finite set S called the state space. The subscripts have the interpretation of time. Therefore given

an integer time t, x0, …, xt are assumed to be known at the time, while xt+1, xt+2, … remain random. For

convenience, we label states with positive integers: S = {1, …, n}, where n is the number of possible states.

(a) Is S a good choice of sample space for describing this stochastic process? No matter what the answer is,

for the rest of the question we assume that a good sample space ? (which might be S if your answer is

“yes”) has been chosen to carry the random variables.

(b) The fundamental assumption of Markov chains is that given x0, …, xt, the probability that xt+1 = j is pji

where i is the value of xt. This holds for every t = 0, 1, … and the numbers pji are independent of t. More

precisely, for any fixed t and the event A that x0 = a0, …, xt = at (where a0, a1, …, at are integers in S),

P(x?1t+1(j) ? A) = P(A)pj,at; this holds for all a0, a1, …, at. (The so-called Markov property means that

the value of xt+1 only depends on xt and not on history further back.)

Let P be the n × n matrix whose (j, i) entry is pji for all i, j ? S; it is called the transition matrix of the

Markov chain. Show that for the probabilities to be well-defined for all laws of x0, each column of P sums

up to one.

(c) A law on the state space S can be represented by an n × 1 matrix (column vector), whose (i, 1) entry is

the probability of {i}. A function f : S ? R can be represented by a 1 × n matrix whose (1, i) entry is

the number f(i). (Notice that f is not a random variable unless your answer to Part (a) is “yes”.) If the

law of x0 is v0, then what is the interpretation of fv0 (matrix product)?

(d) In what follows, fix a law v0 of x0 and a function f : S ? R. What is the law of x1?

(e) Notice that fP is a 1×n matrix, so it represents a function on S. What does that function mean intuitively?

(As we can s
