# Cost-Benefit Analysis

Hi. Please find some multiple choice.

Question 1

A relation known with certainty is called a:

1. statistical relation

2. multiple regression

3. deterministic relation

4. simple regression

Question 2

Statistical analysis of economic relations focuses on the estimation and interpretation of:

1. Sample statistic

2. population parameters

3. summary measures

4. descriptive measures

Question 3

Relative dispersion is measured by the population:

1. range

2. standard deviation

3. variance

4. coefficient of variation

Question 4

A multiple regression model involves two or more:

1. Y variables

2. X variables

3. intercept points

4. data points

Question 5

Generally speaking, population parameters are not known and mustbe estimated by the sample:

1. Mean

2. Mode

3. Median

4. Statistics

Question 6

High correlation among X variables leads to:

1. Multicollinearity

2. High R(squared)

3. Low R (squared)

4. High t statistics

Question 7

Statistics are

1. Descriptive measures for a sample

2. summary measures for the population

3. pre-determined variables

4. endogenous variables

Question 8

When no scatter about the regression line exists:

1. SEE = 0

2. R(Squared)=0

3. t=0

4. F=0

Question 9

The "middle" observation is the;

1. median

2. average

3. mean

4. mode

Question 10

If demand increases while supply decreases for a particular good:

1. its equilibrium price will increase while the uantity of the good produced and sold could increase, decrease, or remain constant.

2. the quantity of the good produced and sold will decrease while its equilibrium price could increase, decrease, or remain constant.

3. the quantity of the good produced and sold will increase while its equilibrium price could increase, decrease, or remain constant.

4. its equilibrium price will decrease while the quantity of the good produced and sold could increase, decrease, or remain constant.

#### Solution Preview

Question 1

A relation known with certainty is called a:

1. statistical relation

2. multiple regression

3. deterministic relation

4. simple regression

deterministic relation: This holds true according to a preconceived formula or rule.

Question 2

Statistical analysis of economic relations focuses on the estimation and interpretation of:

1. Sample statistic

2. population parameters

3. summary measures

4. descriptive measures

Sample statistic: This is a measure computed from a sample of observations from the population of interest.

Question 3

Relative dispersion is measured by the population:

1. range

2. standard deviation

...
