-
The number of coins that Jake spots when walking to work can be modeled as a Poisson process with unit rate of 3/half an hour. Suppose it takes Jake half an hour each day to walk to work, and half an hour to walk back. Each coin is equally likely to be a penny, a nickel, a dime, or a quarter. Jake ignores the pennies but picks up the other coins.
(a) Find the expected amount of money that Jake picks up on his way to work. (b) Find the variance of the amount of money that Jake picks up on a given day. (c) Find the probability that Josh picks up exactly 5 cents on his way to work. You do not have to calculate this. Just provide an expression.

The number of people arriving for treatment at an emergency room
can be modeled by a Poisson process with a rate parameter of 5 per
hour. In other words, the mean number of people arriving in one
hour is 5. (Use R)
(a) What is the probability that exactly four arrivals occur
during a particular hour?
(b) What is the probability that at least 4 people arrive during
a particular hour?
(c) What is the probability that at most 4...

The number of new businesses established in the US since
1990 can be modeled by the function
Nx=110.8x^3-5305.5x^2+76,701x+332,892 where x = 0 represents 1990
and the domain is [0, 25].
Use the First Derivative Test to determine the extrema of the
function on the given domain. Classify as max/min and
absolute/relative. For what intervals does the function
increase/decrease? Please label and interpret each answer in the
context of this problem.

In his current job, Jake can work as many hours per day as he
chooses and is paid $10 per hours. Faced with this wage schedule,
he chooses to work 12 hours per day. A law has just been passed
requiring employers to pay double wages for any hours in excess of
8 hours. True/False: Assuming that leisure is a normal good for
Jake, he will certainly work more than 12 hours per day. With the
use of an appropriate...

Consider a circular board game with 4 spots along its
circumference. Each time, tosstwo fair coins. For each Heads you
obtain, move one spot clockwise. If you do not get any Heads, then
move one spot counterclockwise. Repeat.
a) Define your states to model this game a discrete-time Markov
chain (DTMC).
b) Verify that process {Xn, n = 0, 1, 2, ...} is a discrete-time
Markov chain. Briefly discuss.
c) Derive a transition probability matrix P. Briefly explain how

In a certain species of moth, there are two variations in the
number of black spots on the wings, either 2 or 4, which appear to
be the result of a single gene.
Scientists hypothesize that 4 spots is dominant to two spots.
They cross two individuals that appear to be heterozygous for this
trait and 140 offspring are produced.
If 4 spots is in fact dominant:
1. how many would be expected to display 4 spots?
2. how many would...
