Wenatchee is a town on a large river. On the other side of the river is East Wenatchee (since the river is the county line, these are in two different counties and thus, two different cities.) Wenatchee (which I refuse to call "West Wenatchee") is pretty much hemmed in on all sides by mountains. East Wenatchee, on the other hand, sits on a large plateau surrounded by wheat fields.

Assume that housing in Wenatchee and housing in East Wenatchee are what economists call "perfect substitutes." This means basically that people don't care whether they live in Wenatchee or East Wenatchee. Then imagine that in the nearest big city there is a pandemic followed by a bunch of riots. Part of the town is taken over by Marxists revolutionaries. The city starts dismantling the police and raising taxes because they have no money. (Just try to imagine it!) and this causes a lot of people to decide it would be nice to live in a smaller town on the other side of the mountains.

Which will grow more, Wenatchee or East Wenatchee? Why? Your answer should include econ words like "supply," "demand," "quantity supplied," "quantity demanded," and a certain important word from chapter 5. It should also probably include a graph or two.

It is estimated that in a school 35% of the pupils play an instrument, 30% of the pupils attend the school Art club and 10% of the pupils do both, play an instrument and attend the school Art club. Every pupil chooses which activity to do independently of other pupils. We randomly choose 10 pupils from the school and record for each pupil whether they play an instrument and/or attend the school Art club.

(a) Describe an appropriate sample space.

(b) Compute the probability that among randomly chosen 10 pupils, exactly 4 pupils play an instrument and attend the school Art club, exactly 3 play an instrument but do not attend the school Art club and exactly 2 neither play an instrument nor attend the school Art club. Justify your answer.

(c) If among the randomly chosen 10 pupils at least 2 play an instrument compute the probability that at least 1 pupil does both activities.

An X-linked recessive allele, r, produces red-green colorblindness in humans. A normal woman whose father was colorblind marries a colorblind man.

a. What is the chance that the first child from this marriage will be a colorblind boy?

b. What is the chance that the first child from this marriage will be a colorblind girl?

c. If the couple have three children, what is the probability that two of them will be colorblind boys and one will be a normal child (boy or girl)?

Founded in 1983, Beverly Hills Fan Company is located in Woodland Hills, California. With 23 employees and sales of less than $10 million, the company is relatively small. Management feels that there is potential for growth in the upscale market for ceiling fans and lighting. They are particularly optimistic about growth in Mexican and Canadian markets. Presented below is information from the president’s letter in the company’s annual report. “An aggressive product development program was initiated during the past year resulting in new ceiling fan models planned for introduction this year. Award winning industrial designer Ron Rezek created several new fan models for the Beverly Hills Fan and L.A. Fan lines, including a new Showroom Collection, designed specifically for the architectural and designer markets. Each of these models has received critical acclaim, and order commitments for this year have been outstanding. Additionally, our Custom Color and special fans continued to enjoy increasing popularity and sales gains as more and more customers desire fans that match their specific interior decors. Currently, Beverly Hills Fan Company offers a product line of over 100 models of contemporary, traditional, and transitional ceiling fans.” Instructions: What points did the company management need to consider before deciding to offer the special-order fans customers? How would incremental analysis be employed to assist in this decision?

Dr. Camille Saroyan is a forensic pathologist who specializes in identifying cause of death when the cause is unknown. She wants to know if the best interns for her lab come from private universities or public universities. Dr. Saroyan creates two matched groups of potential interns. She matches the interns on board scores, gender, and GPA. The only difference between the two groups is whether they went to school at a private university or a public university. Dr. Saroyan has all the interns examine the same cases and scores them on how well they do at determining cause of death.

"DRESS CODE"

I NEED YOUR OPINION ABOUT THIS SITUATION, PLEASE WRITE A PARAGRAPH IN THE FORM OF FORMAL ESSAY. THANKS.

THIS IS ABOUT GRADUATE SCHOOL NOT UNDERGRADUATE

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The school has a dress code policy. Students start to be absent and the absent rate increased, thus school changed policy and let the students wear casual attire for 1 day a week, in this case; the absent rate dropped. School decided to change the policy for Art students and let them wear casual attire for 3 days a week, so the school realized the absent rate incredibly decreased.

What is your opinion about this situation? Please write a paragraph in form of "Formal Essay".

(Please note that the school has Dress Code policy and wants to know that you will be a good fit in this school)

Thanks!

Financial econometrics } A new discipline with new methods

Robert Engle

Department of Economics, University of California at San Diego, 9500 Gilman Drive, La Jolla, CA 92093-0508, USA and Stern School of Business, New York University, 44 West 4th Street, Suite 9-160, New York, NY 10012, USA

Financial econometrics is simply the application of econometric tools to "nancial data. For many years, least-squares techniques provided satisfactory tools. Stock market forecasts, e$cient market tests, and even tests of portfolio models such as the CAPM and APT were essentially implemented with least squares on cleverly manipulated data sets. More recently, however, the "eld has developed its individual character as new statistical tools have been invented to analyze new questions.
