In analyzing hits by bombs in a past war, a city was subdivided into 457 regions, each with an area of 0.25-km². A total of 356 bombs hit the combined area of 457 regions. The Poisson distribution applies because we are dealing with the occurrences of an event (bomb hits) over some interval (a region with area of 0.25-km².

In analyzing hits by bombs in a past war, a city was subdivided
into 457 regions, each with an area of 0.25-km². A total of 356
bombs hit the combined area of 457 regions. The Poisson
distribution applies because we are dealing with the occurrences of
an event (bomb hits) over some interval (a region with area of

In analyzing hits by bombs in a past war, a city was subdivided
into 487 regions, each with an area of 1-mi². A total of 389 bombs
hit the combined area of 487 regions. The Poisson distribution
applies because we are dealing with the occurrences of an event
(bomb hits) over some interval (a region with area of 1-mi².
Find the mean number of hits per region:
mean =
Find the standard deviation of hits per region:
standard deviation =...

In analyzing hits by bombs in a past war, a city was subdivided
into 471 regions, each with an area of 0.5-km². A total of 390
bombs hit the combined area of 471 regions. The Poisson
distribution applies because we are dealing with the occurrences of
an event (bomb hits) over some interval (a region with area of
0.5-km².

Joey Louzeshot is practicing his dart throwing skills. In the
past, he hits the bullseye on the target only one time for every
200 throws. To practice, he will throw darts on Sunday and
Monday.
e) On Monday, Joey will practice by throwing the dart until hits
the bullseye, then he will quit practicing. Let A be the number of
attempts until he hits the bullseye. What are the distribution,
parameter(s) and support of A?
f) What is the expected...

For the past
112112
years, a certain state suffered
2828
direct hits from major (category 3 to 5) hurricanes. Assume
that this was typical and the number of hits per year follows a
Poisson distribution. Complete parts (a) through (d).
(a) What is the probability that the state will not be hit by
any major hurricanes in a single year?
The probability is
1-The number of hits to a website follows a Poisson process.
Hits occur at the rate of...

For the past 104 years, a certain state suffered 27 direct hits
from major (category 3 to 5) hurricanes. Assume that this was
typical and the number of hits per year follows a Poisson
distribution. Complete parts (a) through (d). a) What is the
probability that the state will not be hit by any major hurricanes
in a single year? The probability is nothing. (Round to four
decimal places as needed.) (b) What is the probability that the
state will...

During the World War II, rockets were fired to attack the city
of London. To manage the crisis, London was subdivided into many
identical regions. Ambulances and fire fighters were assigned in
each region to observe the number of rocket hits while providing
rescue. At the same time, statisticians predicted the number of
rocket hits follows Poisson distribution. Using goodness of fit
test, test whether or not the number of rocket hits follows a
Poisson distribution at α=5%.
Number of...
