Question

The
annual fuel cost is an estimate assuming 15,000 miles of travel a
year (55% city and 45% highway) and an average fuel price .

a) what are the individuals data set?

b) For each individuak, what variables are given? which of
these variables are categorical, and which are quantitative? in
what units are the quantitative measured?

Answer #1

**Answer:**

Based on annual driving of 15,000 miles and fuel efficiency of
20 mpg, a car in the United States uses, on average, 750 gallons of
gasoline per year. If annual automobile fuel usage is normally
distributed, and if 21.77% of cars in the United States use less
than 500 gallons of gasoline per year, what is the standard
deviation?

The Municipality of a city wants to
estimate the daily expenditure of the fuel consumption for city’s
garbage removal.
The city contains a business part and
a residential part. City officers believe that, the amount of the
fuel Y (in thousands of liters)
depends on the weight of the garbage (in
Tons) in the two parts of city x1
and x2. A random sample is collected for six days
and the data was as follows:
y

Gas Mileage
The cost of fuel is largest component of cost of ownership for
most vehicles. Fuel cost is (almost) inversely proportional to gas
mileage; higher gas mileage means lower fuel cost and vice-versa.
If you keep track of the number of miles driven on each tank of gas
as well as how much gas is purchased, it is easy to calculate gas
mileage; many cell phone apps exist to track this. The data on the
second page is the...

The goal is to estimate annual
equivalent cost of car ownership.
General outline.
find a price quote for a new vehicle, resale price for the same
model, annual maintenance cost and gas expenses;
assume annual mileage to obtain annual gas expense;
time of ownership of two vehicles should not be equal.
Some hints.
you can use www.edmunds.com, www.canadianblackbook.com or any
other website of your choice to choose two cars you wish to
compare. You can use the same website to...

Based on information from the Federal Highway Administration web
site, the average annual miles driven per vehicle in the United
States is 13.5 thousand miles. Assume σ ≈ 650 miles. Suppose that a
random sample of 36 vehicles owned by residents of Chicago showed
that the average mileage driven last year was 13.2 thousand miles.
Would this indicate that the average miles driven per vehicle in
Chicago is different from (higher or lower than) the national
average? Use a 0.05...

Insurance rates depend on such different variables; for example,
the city where the user lives, the number of cars he has and the
company in which he is insured. The website www.insurance.ca.gov
reports the 2010 annual premium for a man, licensed to drive for
6-8 years, who drives a Honda Accord for 12,600 to 15,000 miles per
year and has had no violations no accidents.

1. A city with 4% unemployment and no inflation is considering
building a new stadium for its professional football team. The team
currently plays in an old stadium owned by the city. If a new
stadium were to be built, it would cost city $400M (M for million)
to demolish the old one and build the new one. The new stadium
would be expected to last for 40 years and the city would finance
the costs of the project by...
