Unformatted text preview: claims at times of a Poisson process with
rate 4 per week. Writing K as shorthand for “thousands of dollars,” suppose
that the mean payment is 10K and the standard deviation is 6K. Find the mean
and standard deviation of the total payments for 4 weeks.
2.36. Customers arrive at an automated teller machine at the times of a Poisson
process with rate of 10 per hour. Suppose that the amount of money withdrawn
on each transaction has a mean of $30 and a standard deviation of $20. Find
the mean and standard deviation of the total withdrawals in 8 hours.
2.37. As a community service members of the Mu Alpha Theta fraternity are
going to pick up cans from along a roadway. A Poisson mean 60 members show
up for work. 2/3 of the workers are enthusiastic and will pick up a mean of 10
cans with a standard deviation of 5. 1/3 of the workers are lazy and will only
pick up an average of 3 cans with a standard deviation of 2. Find the mean
and standard deviation of the the number of cans collected.
2.38. Let St be the price of...
