In this section you have discussed taking samples. For this post you will plan how you will take a sample. At NCSU there are approximately 31,000 students and about 7,000 faculty and staff. We would like to compare the cars of students with those of faculty/staff. Specifically we would like to determine if the average mileage (odometer reading NOT MPG)  for students’ cars is higher than that of faculty/staff cars. To answer this question we need to collect a sample of cars from each group. In this post you should explain how you would carry out this sample. The sample should consist of 200 subjects with at least 100 subjects from each group. You should explain how you will select this sample and how you would collect the information. You should be complete but you should also be concise. Explain the important details that may be relevant. Your post should be approximately 2 to 4 paragraphs.

The following question is based on the lifetime of muon lab.

(i) The muons whose decays we observe are born outside the detector and therefore spend some (unknown)
portion of their lifetime outside the detector. So, we never measure the actual lifetime of any muon.
Yet, we claim we are measuring the lifetime of muons. How can this be? In addition to this, Why do the lifetimes of positive and negative muons differ?

(ii)The timeout interval for the experiment was found to be 20.02 microseconds. What does the timeout interval of the FPGA imply about the maximum time between signal pulses when conducting the lab? Please explain this part in detail.

(iii) Explain the behaviour of the muon rate reported by the software as the discriminator threshold and
HV setting are varied. (Note that during the experiment, the muon rate decreased for both) Why is this?

(b) You have been employed as a network administrator in an organization. If you have to send the data of your organization through the internet (there might be very untrusty network nodes), what kind of encryption will you use? Further, sometimes attackers exploit a special feature of the transport layer (segmentation and reassembly) to launch an attack. What attack is this? (c) Of the various firewall types available for use in a business network, which type collects network connection information and maintains dynamic state tables used for subsequent connections and which enables ports to be opened and closed as needed? Explain. Further, why is it so difficult to stop DDoS attacks by blocking the attacking IP addresses?

Question: A survey was conducted to attempt to determine how many hours the typical worker works during one year in the US. A survey of 33 workers found the mean number of hours worked in a year to be 1784 hours with a standard deviation of 65 hours.

a. Predict the actual mean number of hours worked by a worker in the US. State your answer using appropiate statistical terminology.

b. Explain what this answer means to someone who has never taken statistics, that is avoid statistical jargon and use common language. Use complete sentences.

*note: please give a step by step explanation for explaining what you did and why

One morning at breakfast, you notice your five-year-old son’s face appears bright red, as if he had been slapped. Upon closer inspection, you see that the redness is due to many tiny, red bumps on the skin. His arms and legs are also covered with this rash (though less than the face), with just a few bumps on the torso. He feels fine and doesn’t seem ill. He had chickenpox when he was 3 and all his immunizations are up to date. His throat looks normal with no redness, and he says it isn’t sore, either. He has had a runny nose for the last few days, but other than that he has seemed fine.
    1. What is your diagnosis? Why did you check his throat?

    2. Should he go to school today? Why or why not?

    3. Is this a rare infection? Explain.

    4. Are any sequelae associated with this infection? If so, name them

1.) What would a trauma therapist say about the Loftus memory experiments which seem to cast doubt on the possibility of repressed memories?  What would Loftus say?  Who is more correct in your opinion?

2.) Do you think mental development is mostly due to biological brain growth or social factors (Use Piaget and his critics to answer this question)?

3.) Explain the serial position effect and how it can be tested/demonstrated. In addition, explain the dichotic listening task and mention some of the typical findings.

Toledo Stadium

The city of Toledo has received a proposal to build a new multipurpose outdoor sports stadium. The expected life of the stadium is 20 years. It will be financed by a 20-year bond paying 8 percent interest annually. The stadium's primary tenant will be the city's Triple-A baseball team, the Red Hots. The plan's backers anticipate that the site also will be used for rock concerts and college and high school sports. The city does not pay any taxes. The ciy's cost of capital is 8 percent. The costs and estimated revenues are presented next:

Cash Outflows

Construction costs             $12,000,000

General maintenance (including labor)                                $250,000 per year

Cash Inflows

Red Hots' lease payment                                                   $650,000 per year

Concerts                                                                           $600,000 per year

College and high school sports                                           $50,000 per year

Required:

A. Should the city build the stadium? (Assume payments are made at the end of the year)

B. The Red Hots have threatened to move out of Toledo if they do not get a new stadium. The city comptroller estimates that the move will cost the city $350,000 per year for 10 years in lost taxes, purking, and other fees. Should the city build the stadium now? State your reasoning.
