Question

Find the P-value for the indicated hypothesis test.

An airline claims that the no-show rate for passengers booked on its flights is less than 5%. Of 380 randomly selected reservations, 18 were no-shows. Find the P-value for a test of the airline's claim. Round to 2 decimals

Answer #1

Let p denotes the true proportion of no show.

ans-> p-value = 0.41

An airline claims that the no-show rate for passengers is less
than 10%. In a sample of 420 randomly selected reservations, 19
were no-shows. A α = 0.05, test the airline's claim.

An airline claims that the no-show rate for passengers is less
than 8%. In a sample of 419 randomly selected reservations, 22 were
no-shows. At α = 0.01, test the airline's claim.
A.
P-value = 0.026 > 0.01; do not reject H0; There is not enough
evidence to support the airline's claim, that is less than 8%
B.
P-value = 0.019 > 0.01; do not reject H0; There is not enough
evidence to support the airline's claim, that is less...

. A bus line claims that the no-show rate for passengers is at
most 8%. In a sample of 360 randomly selected reservations, 38 were
no-shows. At α = 0.05, test the bus line’s claim.

An airline's public relations department says that the airline
rarely loses passengers' luggage. It further claims that on those
occasions when luggage is lost,
93 %93%
is recovered and delivered to its owner within 24 hours. A
consumer group who surveyed a large number of air travelers found
that only
116116
of
164164
people who lost luggage on that airline were reunited with the
missing items by the next day. Does this cast doubt on the
airline's claim? Explain.

An airline claims that its flights are consistently on time with
an average delay of at most 11 minutes. It claims that the average
delay is so consistent that the variance is no more than 92
minutes. Doubting the consistency part of the claim, a disgruntled
traveler calculates the delays for his next 25 flights. The average
delay for those 25 flights is 23 minutes with a standard deviation
of 17 minutes. Assume α = 0.05. Is the traveler disputing...

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.

asked 30 randomly selected people if they like playing
soccer. Of those, 18 responded positively. To determine
if 45% of the people like soccer in that country, the
news channel conducted a hypothesis test as follows:
