This problem is from 2008.

The US Open is an annual two week tennis event in Flushing NY in late August, early September.

In a year with no significant rain interruption, the US Open makes approximately $275 million in revenue and incurs expenses of approximately $225 million, for a profit of $50 million. Of the $275 million in revenue approximately $100 million is from ticket sales. As a non-profit organization, it incurs no tax.

The US Open can work around rain delays but if all play is suspended in either the afternoon or evening sessions, tickets are good for the same session in the following year, in which case the USTA foregoes revenue. The largest ticket prices are for the women’s and men’s finals so a rain-out on either of these days forgoes the most revenue.

The Open is interested in buying a contract to protect itself from foregone revenues from rain interruptions during the finals. Working with its insurance broker, it approaches the insurance market to see if it can buy a weather derivative or insurance policy.

The US Open estimates that between foregone ticket sales and lost margin on concessions and broadcasting rights, a rain out on either the men’s or women’s finals will mean $30 mil in lost profits.

The insurance broker is able to secure an insurance policy that will indemnify the US Open if rainfall occurs during the men’s or women’s finals. The policy treats each event separately, meaning there is coverage and a corresponding premium charged for postponement of either final. The insurer is willing to provide a policy covering each separate event that will indemnify the US Open with a limit of $30 million and a policy premium of $10 million for each. As with all insurance policies, the US Open can collect the insurance payments only once it demonstrates the losses.

The weather desks at three major reinsurance holding companies with broker/dealers supply the probabilities associated with significant rainfall (> ¼ inch) on days 13 and 14 of this calendar year, which is 20% for either day, and conditional on rain on the 13th day, the chance of rain on the 14th day is 30%.

Write out all possible rain/dry possibilities for the 13th and 14th days, with their associated probabilities.

Without insurance, what are the profits if there are rain postponements to either or both finals?

Without insurance, what are the expected profits?

With insurance, what are profits if there are rain postponements?

With insurance what are profits if there is no rain?

What are the expected profits if insurance is purchased?

Should the US Open explore including additional days into the policy?

Over a ten year period, assuming baseline revenue and costs are approximately the same amounts as today, what would the US Open expect to earn (i) in the absence of an insurance policy and (ii) with the insurance policy?

The weather desk is also willing to write two weather derivative contracts, one for day 13 and one for day 14, each with a payout of $30 million and a cost of $12 million. The derivative pays the US Open regardless of whether play is suspended or not. It pays based on measured rainfall within 24 hour period exceeding ¼ of an inch.

What is the best strategy for the US Open to manage its exposure to rain?

Explain.

Two hospital emergency rooms use different procedures for triage of their patients. A local health care provider conducted a study to determine if there is a significant difference in the mean waiting time of patients for both hospitals. The 40 randomly selected subjects from Medina General Hospital (population 1) produce a mean waiting time of 18.3 minutes and a standard deviation of 2.1 minutes. The 50 randomly selected patients from Southwest General Hospital (population 2) produce a mean waiting time of 19.2 minutes and a standard deviation of 2.92 minutes. Using a significance level of α = .02, the critical value(s) for rejecting the null hypothesis is(are) -2.33 ±1.988 +2.33 -2.37 ±2.33 +2.37 ±2.37 +1.988 -1.988

Let p be the (unknown) proportion of males in a town of 100, 000 residents. A political scientist takes a simple random sample of 100 residents from this town.

(a) Write down the exact pmf, as well as an approximate pmf, for the number of males in the sample. (They should both depend on p).

(b) If the number of males in the sample is 55 or more, the political scientist will claim that there are more males than females in the town. If the number of males in the sample is less than 55, he/she will claim that the number of males in the town is smaller or equal to that of females. What is approximately the probability that his/her claim will be correct if the true proportion of males in the town, p, is 50%? What if p = 55%?

(c) Report an approximate 68% confidence interval for p if 65 of the 100 residents in the sample are male.

The sinking of the RMS Titanic is one of the most infamous shipwrecks in history. On April 15, 1912, during her maiden voyage, the Titanic sank after colliding with an iceberg, killing 1502 out of 2224 passengers and crew. This sensational tragedy shocked the international community and led to better safety regulations for ships. One of the reasons that the shipwreck resulted in such loss of life was that there were not enough lifeboats for the passengers and crew. Although there was some element of luck involved in surviving, some groups of people were more likely to survive than others.
The file Titanic.xls contains data for 1309 of the Titanic passengers. Each row represents one person. The columns describe different attributes about the person including whether they survived (survived), their gender (sex), and their passenger-class (pclass). You can find a short description of each variable in the variables worksheet included in the file.


Answer the following based on the dataset:
a. What percentage of the men suvived? What percentage of the women survived?
b. What was the average fare for each passenger class?
c. Compare the survival rates of each class of passengers.

1.8 Xr01-08 The owner of a large fleet of taxis is trying to estimate his costs for next year’s operations. One major cost is fuel purchase. To estimate fuel purchase, the owner needs to know the total distance his taxis will travel next year, the cost of a gallon of fuel, and the fuel mileage of his taxis. The owner has been provided with the first two figures (distance estimate and cost of a gallon of fuel). However, because of the high cost of gasoline, the owner has recently converted his taxis to operate on propane. He has measured and recorded the propane mileage (in miles per gallon) for 50 taxis.

a.What is the population of interest?
b. What is the parameter the owner needs?

c. What is the sample?
d. What is the statistic?

e. Describe briefly how the statistic will produce the kind of information the owner wants.
