(b)
To determine
Define sample
(b)
Expert Solution
Explanation of Solution
A subset or portion of the population that is actually obtained and that is used to draw conclusions about the population is called a sample.
(c)
To determine
Define parameter.
(c)
Expert Solution
Explanation of Solution
Parameter refers to any statistical measure that is based on all units in the population.
(d)
To determine
Define statistic.
(d)
Expert Solution
Explanation of Solution

Consider the market for electricity. Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living
downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand
(private value) curve and the supply (private cost) curve for electricity.
Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.

QUANTITY (Units of electricity)
Social Cost
The market equilibrium quantity is
units of electricity, but the socially optimal quantity of electricity production is
units.
To create an incentive for the firm to produce the socially optimal quantity of electricity, the government could impose a
unit of electricity.
