Consider researching the maximum distance that prospective professional quarterbacks can throw a football. Suppose that 41 NFL draft prospect quarterbacks were asked to throw a football as far as they could. For this sample, the mean distance was 68.9 yards and the sample standard deviation was 5.2 yards. Find a 90% confidence interval for the true mean maximum distance that the population of NFL prospect quarterbacks can throw a ball. Also, find a 90% confidence interval for the true population standard deviation of distances. Suppose professional blowhard Skip Bayless claimed the true mean distance was less than 70 yards. Use a hypothesis test (with significance level 0.05) to determine whether we can conclude that Bayless's claim is accurate, based on these data.

bulls eye:
a.) At least 190 times?
b.) No more than 180 times?
c.) between 150 and 185 times (including 150 and 185)?

Consider the same football situation as in the previous
question, but now suppose the payoffs (probabilities of winning)
are as given in the following normal form:
Defense
Defend Pass
Defend Run
Offense
Pass
0.2, 0.8
0.3, 0.7
Run
0.5, 0.5
0.4, 0.6
Do any of the teams (the one playing defense or the one playing
offense) has a dominant strategy? Which one? Explain why.

Consider a surface that has N sites each of which can adsorb one
gas molecule. suppose that it is in contact with a gas with the
chemical potential u. Assume that an adsorbed molecule has energy
-e0 compared to one in the gas phase. Show that the surface
coverage T (the ratio of adsorbed molecules to adsorbing sites) is
given as
T=1/(exp(-(u+e0)/kT)+1). (Hint: You can ignore the volume change
upon adsorption, which means that the Gibbs free energy is equal...

2.10) Consider the system of Conceptual Problem
2.9 (please see below). Now suppose the machine can process two
items simultaneously. However, it takes 2 minutes to complete the
processing. There is a bin in front of the machine where there is
room to store two nondefective items. As soon as there are two
items in the bin, they are loaded onto the machine and the machine
starts processing them. Model this system as a DTMC.

c. Suppose that Renee’s revenue includes $5 million of business interest income. What is the maximum amount of business interest expense that Renee can deduct this year?
Renee operates a proprietorship selling collectibles over the web, and last year she purchased a building for $24 million for her business. This year, Renee’s proprietorship reported revenue of $85 million and incurred total expenses of $78.1 million. Her expenses included cost of goods sold of $48.5 million, sales commissions paid of $16.9 million, $10.5 million of interest paid on the building mortgage, and $12.7 million of depreciation.
