1) The table shows the amounts of crude oil (in thousands of barrels per day) produced by a certain country and the amounts of crude oil (in thousands of barrels per day) imported by the same country for seven years. The equation of the regression line is
y = -1.339x+17,009.89.
Complete parts (a) and (b) below.
Produced, x Imported, y
5,831 9,336
5,674 9,191
5,575 9,676
5,408 10,008
5,236 10,108
5,174 10,178
5,037 10,053
(a) Find the coefficient of determination and interpret the result.
r2=
- How can the coefficient of determination be interpreted?
(b) Find the standard error of estimate and interpret the result.
s=
- How can the standard error of estimate be interpreted?
Solutions
Expert Solution
(a) Find the coefficient of determination :
Coefficient of determination is show that the ralation between dependent variable and other independent variable ,
coefficient of determination =r2=0.7982
Interpretion :
About 79.82 % of the variation in the amounts of crude oil imported by the same country for seven years can be explained by the number the amounts of crude oil produced by a certain country .
Excel Calculation :
(b) The standard error of estimate and interpret the result.
s=s/sqrt(5)
s=195.41
The standard error of estimate of the 195.41 is the amount f crude oil produced by a certain country

chandler Oil has 5000 barrels of crude oil 1 and 10,000 barrels
of crude oil 2 available. Chandler sells gasoline and heating oil.
These products are produced by blending the two crude oils
together. Each barrel of crude oil 1 has a quality level of 10 and
each barrel of crude oil 2 has a quality level of 5.6 Gasoline must
have an average quality level of at least 8, whereas heating oil
must have an average quality level of...

An oil producer plans to sell 1 million barrels of crude oil one
year from now. The oil price in one year is normally distributed
with the mean of $80 per barrel and the standard deviation of $12
per barrel. What is the probability that the sales revenue is lower
than $50 millions
A)0.62%

A country imports 3 billion barrels of crude oil per year and
domestically produces another 3 billion barrels of crude oil per
year. The world price of crude oil is $90 per barrel. An imposition
of a $30 per barrel import fee on crude oil that would involve
annual administrative costs of $250 million. Assume that the world
price will not change because of the country imposing the import
fee, but that the domestic price will increase by $30 per...

2) A country imports 3 billion barrels of crude oil per year and
domestically produces another 3 billion barrels of crude oil per
year. The world price of crude oil is $90 per barrel. Assuming
linear schedules, economists estimate the price elasticity of
domestic supply to be 0.25 and the price elasticity of domestic
demand to be -0.5 at the current equilibrium.
a. Consider the changes in social surplus that would result from
imposition of a $30 per barrel import...

A country imports 3 billion barrels of crude oil per year and
domestically produces another 3 billion barrels of crude oil per
year. The world price of crude oil is $18 per barrel. Assuming
linear schedules, economists estimate the price elasticity of
domestic supply to be 0.25 and the price elasticity of domestic
demand to be − 0.10 in the neighbourhood of the current
equilibrium. a. Assuming that the world price of crude oil does not
change when the country...

Statoil sold 1 million barrels of crude oil to the Norwegian
petrol station chain, Circle K, today for 120 Nok per barrel (Nok
denotes the Norwegian Krone). Statoil expects to receive the full
payments from Circle K in 3 months’ time when the crude oil is
delivered to Circle K’s facilities in Norway. Statoil is informed
that Circle K will pay for the oil in Norwegian Krone. Ari is asked
by the Chief Financial Officer (CFO) about thestrategy to reduce...

(3) The US produces about 12 million barrels of
oil per day and consumes about 22 million barrels per day (mbpd).
Global production and consumption are about 100 mbpd. About 0.75
mpbd come from federal land, and about 1.75 mbpd come from federal
waters (primarily the Gulf of Mexico). The current oil price is
about $50, the elasticity of oil supply is 0.1 and the elasticity
of oil demand is -0.2.
a. Using these numbers, calculate the long-term
effect on...
