You are given the following information:

The current price of copper is $83 per 100 lbs. The term structure of interest rates is flat at 5% per year continuously compounded. Assume there are no costs associated with storing copper and that the trader can borrow and lend at the riskless rate. The convenience yield for all maturities is 7% per year continuously compounded. Consider a forward contract in which the short position has to make two deliveries: 10,000 lbs of copper in one month and 10,000 lbs of copper in two months. The common delivery price is P. That is the short receives P dollars for delivery after one month and another P dollars for delivery after two months. Establish the fair value of this unusual forward contract. That is find the value for P. make sure to define all terms and to carefully explain how you arrived at your answer.

An unprepared student must take a 7-question, multiple-choice test that has 5 possible answers per question. If the student can eliminate two of the possible answers on the first three questions, and if she guesses on every question, what is the probability that she will answer at least one question correctly?

7) Personal phone calls received in the last three days by a new employee were 4, 1, and 8. Assume that samples of size 2 are randomly selected with replacement from this population of three values. a) List the nine different possible samples of size 2 and find the mean of each of them. b) The probability for each sample mean in Part a) is 1/9. Summarize your results in Part a) by construct ing a sampling distribution for these sample means. c) Find the expected value based on Part b). This expected value is also the mean of all the nine sample means found in Part a). d) Find the population mean of the personal phone calls received in the last three days by a new employee: {2, 3, 7} and compare it with your result in Part c).

Psychopaths tend to be cold and calculated, often not worrying about others or consequences so they are typically not anxious. You are curious whether anxiety scores for people are associated with psychopathy scores. To test this you survey 12 undergraduate students on their anxiety level (0 to 100, higher mean more anxious) and their score on a standard psychopathy measure (0 to 40, higher score indicated a higher level of psychopathy). The data is as follows:

3) Explain this relationship in every day terms (what would you say to a person who does not know anything about correlations).

En-range Networks is a startup internet service provider in Japan that is aiming to provide faster internet access to Japanese citizens. The company has recently finished installing its main access node just south of Tokyo and has hired you to conduct speed tests and analyze the results.

To get some intial data, you decide to conduct latency tests from the newly completed node to random servers around the world. Your tests yield the following data:

To analyze this data, you decide to conduct a t-test to see if the mean of this data is above 35 ms, assuming that ?=.05.

What is the p-value of your t-test?

Can you say that the mean of the data is greater than 35?

Rent'R Cars is a multisite car rental company in the city. It is trying out a new "return the car to the location most convenient for you" policy to improve customer service. But this means that the company has to constantly move cars around the city to maintain required levels of vehicle availability. The supply and demand for economy cars, and the total cost of moving these vehicles between sites, are shown below.

a. Find the solution that minimizes moving costs using Microsoft Excel. (Leave no cells blank - be certain to enter "0" wherever required.)

Modern medical practice tells us not to encourage babies to become too fat. Is there a positive correlation between the weight x of a 1-year old baby and the weight y of the mature adult (30 years old)? A random sample of medical files produced the following information for 14 females.

x (lb) 23 27 22 26 20 15 25 21 17 24 26 22 18 19

y (lb) 127 124 117 125 130 120 145 130 130 130 130 140 110 115

(i) Find a 99% confidence interval for β and interpret its meaning. (Round your answers to three decimal places.) lower limit upper limit Interpretation For each pound less a female infant weighs at 1 year, the adult weight increases by an amount that falls within the confidence interval. For each pound more a female infant weighs at 1 year, the adult weight increases by an amount that falls within the confidence interval. For each pound less a female infant weighs at 1 year, the adult weight increases by an amount that falls outside the confidence interval. For each pound more a female infant weighs at 1 year, the adult weight increases by an amount that falls outside the confidence interval.
