A BOTNET is a collection or a network of infectious ‘bots’ i.e. machines. Botnets have become a platform for the infection to the Internet. In this context, elucidate in detail about the Botnet life cycle Diagram and identify the role played by command and control server in the Botnet life cycle. Do any techniques exist to detect Botnets? If yes, exemplify. Cite your sources

Dr. Walter Wendler, President of WTAMU, is trying to decide if and where the University should build a parking garage and gives you the task to evaluate parking needs for WT’s campus. He asks you to distribute a survey that he has created and hands you a survey about campus parking that asks questions such as how often do you use campus parking, which hours do you need parking, what locations is more parking needed, and general parking views. How would you go about distributing the survey? Which sampling method did you choose and why would that be most appropriate? What are the pros and cons of this method? Discuss at least 1 other sampling method you could use to collect your data and explain why you would NOT use this/these. In your answer, be sure in include selection bias, non-response error, sampling error, and measurement error.

Explain how firm and workers " match and mate" or " marry" each other in the labour market when there are many types of jobs offering various levels of risk to the worker.

Using Wikipedia, look up the entry for Sarbanes-Oxley Act. Look over the table of contents and find the section that describes Section 404 and give it a read. Based on your textbook reading and Wikipedia review, briefly respond to the following. What does Section 404 require of management’s internal control report?

The mean number of sick days an employee takes per year is believed to be about 10. Members of a personnel department do not believe this figure. They randomly survey 8 employees. The number of sick days they took for the past year are as follows: 11; 6; 14; 3; 11; 8; 7; 8. Let X = the number of sick days they took for the past year. Should the personnel team believe that the mean number is about 10? Conduct a hypothesis test at the 5% level.

d) State the distribution to use for the test. (Enter your answer in the form z or t_df where df is the degrees of freedom.)

f) What is the p-value? (Round your answer to four decimal places.)

i) Construct a 95% confidence interval for the true mean. Sketch the graph of the situation. Label the point estimate and the lower and upper bounds of the confidence interval. (Round your answers to three decimal places.)

13. A researcher claims that the average age of a woman when she has her first child is still equal to the 1993 mean of 27.1 years. She obtains a random sample of 30 women who had their first child this year and finds the sample mean age to be 28.2 years. Suppose the population standard deviation is 6.4 years. Test the researcher’s claim using α = 0.10.

1. State and label the null and alternate hypotheses.

2. State the critical value(s) for this test and draw a picture of the critical region(s).

3. Find the value of the test statistic.

4. Find the P-value for this test.

5. Find an appropriate confidence interval to use to test this hypothesis. State the confidence level used.

6. State your conclusion of this hypothesis test, citing reasons from all three methods. Be sure to explain your conclusion in the context of the problem.

Tell the following as a story. Use your own words saying each vessel as you would a list of roads you would drive on to get to the shore and back from campus.  

Trace a red blood cell from the left ventricle to the left 5^th toe and back to the left ventricle.

Ms. Brown is a teacher in a first-grade classroom. The students are not wanting to listen and are taking a very long time to clean the room between tasks. She wants to use praise and feedback as her behavior change tool. Taking what you know about reinforcement from this week's readings, how should she go about doing this? Explain your rationale. It is not always the case that people use reinforcement on purpose. Sometimes, the natural contingencies that follow a behavior result in an increase in a potentially unwanted behavior. Describe a time you accidently reinforced a behavior (caused it to increase) and if it turned out to be a good thing or one that needed remedied.

Please answer the question using examples of what you saw in the movie and your own experience. An answer of anything like “Yes I do” or “No I don’t” will not receive credit. a) What is mark-to-market accounting? Explain in a few sentences. b) Why types of companies could justifiably use this accounting method? State type of company and why you believe it would be justifiable. c) How did Enron abuse mark-to-market accounting methods? Please provide at least one example and why you believe there was abuse involved.
