The undergraduate office at has 3 academic advisors. Students
who want to be talk to an advisor arrive at the rate of 12 per hour
according to a Poisson distribution. If all three advisors are
busy, students wait for one of the advisors to become available.
The average time that a student spends with an advisor is 10
minutes. The standard deviation of the time with an advisor is 2.4
minutes. On average, how many students are waiting to see...

advisors. Students who want to be talk to an advisor arrive at the
rate of 12 per hour according to a Poisson distribution. If all
three advisors are busy, Broad students wait for one of the
advisors to become available. The average time that a student
spends with an advisor is 10 minutes. The standard deviation of the
time with an advisor is 2.4 minutes. On average, how many Broad...

At CDE dental office, on average, 30 patients arrive every hour
and are processed at the same rate. Patients wait in line for
registration. On average, it takes 5 minutes for registration, not
including waiting time. A dentist’s assistant sees a patient after
registration and assigns the patient to one of the two tracks, one
for routine cleanings and another for major treatments. On average,
the dentist's assistant spends 20 minutes with each patient. On
average, 2/3 (or 66.67%) of...

On average, 90 patrons arrive per hour at a hotel lobby
(interarrival times are exponential) waiting to check in. At
present there are five clerks, and patrons wait in a single line
for the first available clerk. The average time for a clerk to
service a patron is three minutes (exponentially distributed).
Clerks earn $10 per hour, and the hotel assesses a waiting time
cost of $20 for each hour that a patron waits in line. If needed,
round your...

For a school, the principal expected that a student takes 45
minutes to travel to school on average. Suppose the time taken to
travel to school by a student follows a normal distribution. 100
students are randomly selected from the school for interview and
they took on average 44 minutes to travel to school with a standard
deviation of 15 minutes. 6 of the selected students had lateness
record in the last month.
Construct a 95% confidence interval for the...

At school, students spend an average of 13.38 minutes per class

probability that a randomly selected student spends more than 17
minutes texting in class?
a) 0.8665
b) 0.1335
c) 0.1515

An insurance company has one adjuster in the branch office.
People with claims against the company are found to arrive in a
Poisson fashion during an 8 to 5 workday. Determine the hourly
service and arrival rates using an 8-hour workday. The amount of
time that the adjuster spends with a claimant is exponentially
distributed. Claimants are processed in the order of their
arrival.
