Answer #1

There are 10 flights daily from Bermuda via American Airlines
into Newark International Airport. Suppose the
probability that any one of the flights arriving late is
0.10.
What is the probability that more than 3 flights will be late
today?
What is the probability that fewer than two flights will arrive
late today?
What is the probability that 0 flights will arrive late
today?

Alpha Airline claims that only 15% of its flights arrive more
than 10 minutes late. Let p be the proportion of all of Alpha’s
flights that arrive more than 10 minutes late. Consider the
hypothesis test
H0 :p≤0.15 versus H1 :p>0.15.
Suppose we take a random sample of 50 flights by Alpha Airline
and agree to reject H0 if 9 or more of them arrive late. Find the
significance level for this test.

Consider the probability that more than 92 out of 146 flights
will be on-time. Assume the probability that a given flight will be
on-time is 63%. Approximate the probability using the normal
distribution. Round your answer to four decimal places.

Consider the probability that more than 92 out of 157 flights
will be on-time. Assume the probability that a given flight will be
on-time is 62%.
Approximate the probability using the normal distribution. Round
your answer to four decimal places.

Marty's Barber Shop has one barber. Customers have an arrival
rate of 2.3 customers per hour, and haircuts are given with a
service rate of 4 per hour. Use the Poisson arrivals and
exponential service times model to answer the following
questions:
What is the probability that no units are in the system? If
required, round your answer to four decimal places.
P0 = _____
What is the probability that one customer is receiving a haircut
and no one is...

If the average arrival rate is 10 per hour, and the average time
it takes to help a customer is 5 minutes, then:
Group of answer choices
No customer will ever have to wait: we can help more customers
per hour than arrive
Utilization is less than 100%: we can help more customers per
hour than arrive, but we may have a queue form and customers might
have to wait..
None of the other answers are correct
There can never...
