I need help with the following questions:

1. Based on the Gallant and Duffy (2008) article, why is it important to have one network operating system (NOS) run routers and switches?

2. Based on the Nicholaisen (2007) article, what are the concerns with the current OSI model design? Why is the Clean Slate Internet Project important to lower the impact of Internet organized crime?

3. What are some of the reasons an organization might consider using a Wireless LAN?

4. What type of security issues need to be considered when implementing a Wireless LAN?

1. Based on the Gallant and Duffy (2008) article, why is it important to have one network operating system (NOS) run routers and switches?

As stated in the article by Gallant and Duffy (2008), the network market has changed. Networks used to be for the sake of connectivity. One needed a network with routers and switches in order to have the connectivity; however, networking has changed due the reality that networks are now for the sake of survival. Many companies as well as individuals require a solid working network for the success of the business. With one network operating system (NOS) running the routers and switches, there can be an elimination of third party vendors, such as Cisco, that service and maintain their proprietary equipment. Allowing one NOS to run routers and switches allows reliability, security, and performance that is lacking in other the enterprise switching companies.

2. Based on the Nicholaisen (2007) article, what are the concerns with the current OSI model design? Why is the Clean Slate Internet Project important to lower the impact of Internet organized crime?

Currently the OSI model is Application, Presentation, Session, Transport, Network, Data, and Physical layers. TCP/IP ...

Statistics Part III for Managers: 4 problems

1. If you want to be 95% confident of estimating the population portion to within a sampling error of + 0.02 and there is historical evidence that the population proportion is approximately 0.40, what sample size is needed?
2. In a study of 500 executives, 315 stated that their company informally monitored social networking sites to stay on top of information related to their company .
a. Construct a 95% confidence interval for the proportion of companies that informally monitored social networking sites to stay on top of information related to their company.
b. Interpret the interval constructed in (a).
c. If you wanted to conduct a follow-up study to estimate the population proportion of companies that informally monitored social networking sites to stay on top of information related to their company to within + 0.01 with 95% confidence, how many executives would you survey?
3. The real estate assessor for a county government wants to study various characteristics of single-family houses in the county. A random sample of 70 houses reveals the following:

Heated area of the houses (in square feet): X= 1,759, S=380
42 houses have central air-conditioning
a. Construct a 99% confidence interval estimate for the population mean heated area of the houses.
b. Construct a 95% confidence interval estimate for the population proportion of houses that have central air-conditioning.
4. A quality characteristic of interest for a tea-bag filling process is the weight of the tea in the individual bags. In this example, the label weight on the package indicates that the mean amount is 5.5 grams of tea in a bag. If the bags are under filled, two problems arise. First, customers may not be able to brew the tea to be as strong as they wish. Second, the company may be in violation of the truth-in-labeling laws. On the other hand, if the mean amount of tea in a bag exceeds the label weight, the company is giving away product. Getting an exact amount of tea in a bag is problematic because of variation in the temperature and humidity inside the factory, differences in the density of the tea, and the extremely fast filling operation of the machine (approximately 170 bags per minute). The following data are the weights, in grams, of a sample of 50 tea bags produced in one hour by a single machine:

5.65 5.44 5.42 5.40 5.53 5.34 5.54 5.45 5.52 5.41
5.57 5.40 5.53 5.54 5.55 5.62 5.56 5.46 5.44 5.51
5.47 5.40 5.47 5.61 5.53 5.32 5.67 5.29 5.49 5.55
5.77 5.57 5.42 5.58 5.58 5.50 5.32 5.50 5.53 5.58
5.61 5.45 5.44 5.25 5.25 5.63 5.50 5.57 5.67 5.36

a. Construct a 99% confidence interval estimate for the population mean weight of the tea bags.
b. Is the company meeting the requirement set forth on the label that the mean amount of tea in a bag is 5.5 grams?
c. Do you think the assumption needed to construct the confidence interval estimate in (a) is valid?
