Recent crime reports indicate that 17.3 motor vehicle thefts
occur every hour in Canada. Assume that the distribution of thefts
per hour can be approximated by a Poisson probability
distribution.
a. Calculate the probability exactly
four thefts occur in an hour.(Round the final
answer to 5 decimal places.)

b. What is the probability there are
no thefts in an hour? (Round the final answer to 5
decimal places.)

In Hawaii, the rate of motor vehicle theft is 503 thefts per
100,000 vehicles. A large parking structure in Honolulu has issued
491 parking permits.
(a) What is the probability that none of the vehicles with a
permit will eventually be stolen? (Round λ to 1 decimal
place. Use 4 decimal places for your answer.)
(b) What is the probability that at least one of the vehicles with
a permit will eventually be stolen? (Use 4 decimal places.)

Data from the Motor Vehicle Department indicate that 80%
of all licensed drivers are older than age 25.
a. In a sample of n=50 people who recently received
speeding tickets, 33 were older than 25 years and the other 17 were
age 25 or younger. Is the age distribution for this sample
significantly different from the distribution for the population of
licensed drivers? Use α= 0.05.
b. In a sample of n=50 people who recently received
parking tickets, 36 were...

Data from the Motor Vehicle Department indicate that 80% of all
licensed drivers are older than age 25. In a sample of n = 50
people who recently received speeding tickets, 33 were older than
25 years and the other 17 were 25 or younger. Is the age
distribution for this sample significantly different from the
distribution for the population of licensed drivers? Use α =
.05

Data from the Motor Vehicle Department indicate that 80% of all
licensed drivers are older than age 25. Information on the age of
n = 50 people who recently received speeding tickets was
sourced by researchers who are interested in whether the age
distribution for the sample of drivers who recently received
speeding tickets is different from the age distribution for the
population of licensed drivers.
State your proposed analysis and why you chose that
analysis.

Given the idea of a “market for crime,” for each of the
innovations listed below indicate whether it shifts the victim
response schedule or the offender response schedule, or both, and
how it changes equilibrium crime and precautions:
a. Higher probability of arrest.
b. Cheaper, more effective burglar alarms.
c. More publicity about threats of crime or terrorism.
d. A reduction in moral scruples against community crime.
e. More dead-end streets and more confusing street patterns.
f. More potential criminals...

The Environmental Protection agency requires that the exhaust of
each model of motor vehicle be tested for the level of several
pollutants. The level of oxides of nitrogen (NOX) in the exhaust of
one light truck model was found to vary among individually trucks
according to a Normal distribution with mean 1.45 grams per mile
driven and standard deviation 0.40 grams per mile.
(a) What is the 30th percentile for NOX exhaust, rounded to four
decimal places?
(b) Find the...

Write a script that checks each minute and reports on who logs
in and who logs out.
You can follow the steps below (not the only way):
Using the commands who and cut, extract the list of usernames
currently logged in the system
To check after a minute, the sleep command can be used: sleep
60
Get the new list of users logged in after a minute
For each user in the list;
check if they are in the second...
