Question

**STAT_14_2**

In learning center there is a coffee machine for student
service. The number of machine faults is split into Poisson
distribution.

On a normal day the number of faults is 1 per day and on a busy day
the number of faults is 3 per day.

The probability that a day is a busy day is 0.3, independently of
other days.

A. What is the probability that in normal three days there will
be at least 2 faults all days together?

B. Days Sun to Wed, are ordinary days. It is known that on days Sun
and Mon there were a total of 4 machine failures.

What is the probability that on Wednesday there will be no glitches
at all?

C. What is the probability that on a random day there will be
exactly two machine failures?

Answer #1

There is a machine at the coffee bar in the student center that
permits a student
to place an order for a coffee drink via their cell phone. The
machine produces paper tickets for
the baristas following a Poisson process at a rate of 2 orders per
minute during the morning hours
(8:00a through 11:00a). What is the probability that exactly 360
orders will appear between 8:00a
and 11:00a with exactly 6 of them appearing between 10:30a and
11:00a? Please...

The number of requests for assistance are received by a towing
service at an average steady rate of 4 per hour. If, during a
normal day the requests are received independently of one another,
compute the probability that exactly ten requests are received
during a particular 2-hour period of a normal day. Suppose, that
the dispatcher ignored at least one call between 2:25 and 2:45pm.
What is the probability that no more than one call was received
during this time...

Gubser Welding, Inc., operates a welding service for
construction and automotive repair jobs. Assume that the arrival of
jobs at the company's office can be described by a Poisson
probability distribution with an arrival rate of two jobs per
8-hour day. The time required to complete the jobs follows a normal
probability distribution, with a mean time of 3.2 hours and a
standard deviation of 2 hours. Answer the following questions,
assuming that Gubser uses one welder to complete all...

Gubser Welding, Inc., operates a welding service for
construction and automotive repair jobs. Assume that the arrival of
jobs at the company's office can be described by a Poisson
probability distribution with an arrival rate of one job per 8-hour
day. The time required to complete the jobs follows a normal
probability distribution, with a mean time of 5.5 hours and a
standard deviation of 2 hours. Answer the following questions,

Consider an online store where a number of customers visit and
buy a product every hour. Let X be the number of people
who enter the store per hour.
The store is active for 14 hours per day, every day of the week.
It is calculated from data collected that the average number of
customers per hour is 10.
(a) When is it appropriate to
approximate a Poisson Distributed random variable with a Normal
Distribution? State the appropriate parameters for...

Suppose you ran 50 separate simulations. Each of these
simulations represent a week (7 days) of working with a molding
machine. During each simulation, the average number of the
machine's failures per day was recorded. You observed that the mean
of all of your sample means follows a normal distribution with a
standard deviation of 25 that is, ~N(M, 25). Later you decided to
run a hypothesis testing on the population mean with the
assumptions below and an alpha =...

From
“Just-In-Time” delivery and inventory control in a warehouse, to
customer service at a call center, to line management at
Disneyland, sometimes knowing how many customers you have is not as
important to know how fast they are piling up. In this Project you
will need to collect real world data, use it to build a model, and
then use that model to assess a second set of data that you will
also collect.
First
you need to decide what...
