Question

Allegiant Airlines charges a mean base fare of $85. In addition, the airline charges for making a reservation on its website, checking bags, and inflight beverages. These additional charges average $36 per passenger. Suppose a random sample of 80 passengers is taken to determine the total cost of their flight on Allegiant Airlines. The population standard deviation of total flight cost is known to be $38. Use z-table. a. What is the population mean cost per flight? b. What is the probability the sample mean will be within $10 of the population mean cost per flight (to 4 decimals)? c. What is the probability the sample mean will be within $5 of the population mean cost per flight (to 4 decimals)?

Answer #1

Allegiant Airlines charges a mean base fare of $85. In addition,
the airline charges for making a reservation on its website,
checking bags, and inflight beverages. These additional charges
average $34 per passenger. Suppose a random sample of 70 passengers
is taken to determine the total cost of their flight on Allegiant
Airlines. The population standard deviation of total flight cost is
known to be $39. Use z-table.
b. What is the probability the sample mean will be within $10...

Problem 12-21 (Algorithmic)
South Central Airlines operates a commuter flight between
Atlanta and Charlotte. The plane holds 25 passengers, and the
airline makes a $96 profit on each passenger on the flight. When
South Central takes 23 reservations for the flight, experience has
shown that, on average, two passengers do not show up. As a result,
with 25 reservations, South Central is averaging 23 passengers with
a profit of 23(96) = $2,208 per flight. The airline operations
office has asked...

South Central Airlines operates a commuter flight between
Atlanta and Charlotte. The plane holds 30 passengers, and the
airline makes a $100 profit on each passenger on the flight. When
South Central takes 30 reservations for the flight, experience has
shown that, on average, two passengers do not show up. As a result,
with 30 reservations, South Central is averaging 28 passengers with
a profit of 28(100) = $2800 per flight. The airline operations
office has asked for an evaluation...

In response to the increasing weight of airline passengers, the
Federal Aviation Administration told airlines to assume that
passengers average 190 pounds in the summer, including clothing and
carry-on baggage. But passengers vary: the FAA gave a mean but not
a standard deviation. A reasonable standard deviation is 35 pounds.
Weights are not Normally distributed, especially when the
population includes both men and women, but they are not very
non-Normal. A commuter plane carries 25 passengers. What can we
expect...

Show work in Excel workbook. Maggies Restaurants has noted that
they have a mean average ticket price for food and drinks of $67.
suppose a random sample of 80 tickets is taken to determine the
total cost of their meal and drinks. The population standard
deviation of total meal cost is know to be $22.
What is the probability the sample mean will be within $3 of the
population mean cost per ticket? (to 4 decimals)

A random sample is selected from a population with mean μ = 100
and standard deviation σ = 10.
Determine the mean and standard deviation of the x sampling
distribution for each of the following sample sizes. (Round the
answers to three decimal places.)
(a) n = 8 μ = σ =
(b) n = 14 μ = σ =
(c) n = 34 μ = σ =
(d) n = 55 μ = σ =
(f) n = 110...
