Question

31) The time between telephone calls to cable television
payment processing center follows an [exponential distribution]
with a mean of 1.5 min. Find probability that the time between the
next two calls will be:

a) 45 second or less?

b) Greater than 112.5 sec?

Answer #1

The
time between telephone calls to a cable televisiom service call
center follows an exponential distribution with a mean of 1.5
minutes.
a. What is the probability that the time between the next two
calls will be 48 seconds or less?
b. What is the probability that the between the next two calls
will be greater than 118.5 seconds?

The time between successive arrivals of calls to emergency
service is random variable which
follows exponential distribution. It was observed that on average
calls arrive to emergency
service every four minutes (1 / λ = 4min) and average number of
calls in one minute is λ = 0.25 calls/ 1 min
The probability that the time between successive calls is less
than 2 minutes is ______
A call just arrived to emergency service. The probability that
next call will arrive...

The time between arrivals at a toll booth follows an
exponential distribution with a mean time between arrivals of 2
minutes.
What is the probability that the time between two successive
arrivals will be less than 3 minutes?
What is the probability that the time will be between 3 and 1
minutes?

at call center, calls come in at an average rate of four calls
per minute. Assume that the time elapsed from one call to the next
has the exponential distribution, and that the times between calls
are independent.
a. find the prob. that after a call is received, the next call
occurs in less than 10 sec.
b. Find a 95% confidence interval for the number of calls in a
minute.

The number of telephone calls per unit of time made to a call
center is often modeled as a Poisson random variable. Historical
data suggest that on the average 15 calls per hour are received by
the call center of a company. What is the probability that the time
between two consecutive calls is longer than 8 minutes? Write all
probability values as numbers between 0 and 1.

The time between arrivals of vehicles at a particular
intersection follows an exponential probability distribution with a
mean of 10 seconds. (a) Sketch this exponential probability
distribution.
(b) What is the probability that the arrival time between
vehicles is 10 seconds or less? (Round your answer to four decimal
places.)
(c) What is the probability that the arrival time between
vehicles is 4 seconds or less? (Round your answer to four decimal
places.)
(d) What is the probability of 30...

The number of incoming calls at a telephone exchange is modeled
using a Poisson distribution with mean lambda= 2 per minute a What
is the probability of having five or less calls in a 3 min interval
b Show that given that there were in calls during the first t
minutes the number of calls during the first S<t minutes follows
a binomial with parameters n and s/t

Suppose that the time between successive occurrences of an event
follows an exponential distribution with mean number of occurrences
per minute given by λ = 5. Assume that an event occurs. (A) Derive
the probability that more than 2 minutes elapses before the
occurrence of the next event. Derive the probability that more than
4 minutes elapses before the occurrence of the next event. (B) Use
to previous results to show: Given that 2 minutes have already
elapsed, what is...

The time in minutes for which a student uses a computer terminal
at the computer center of a major university follows an exponential
probability distribution with a mean of 31 minutes. Assume a
student arrives at the terminal just as another student is
beginning to work on the terminal.
What is the probability that the wait for the second student
will be 15 minutes or less (to 4 decimals)?
What is the probability that the wait for the second student...

The exponential distribution is frequently applied
to the waiting times between successes in a Poisson
process. If the number of calls received per hour
by a telephone answering service is a Poisson random
variable with parameter λ = 6, we know that the time,
in hours, between successive calls has an exponential
distribution with parameter β =1/6. What is the probability
of waiting more than 15 minutes between any
two successive calls?
