Answer: D) We are 95% confident that the average taxi fare between Logan Airport and downtown Boston will fall between $20.51 and $24.21.

Explanation:

The Confidence interval allows one to speculate between which values the average of a population will be. In a 95% confidence interval, this means that we are 95% certain that the average value of a variable will be between the higher and lower limits set by the interval.

The 95% confidence interval here has an upper limit of  $24.2091 and a lower limit of $20.5051 for taxi fares from Logan Airport to downtown Boston. This means that with a 95% certainty, the taxi charge from Logan Airport to downtown Boston will be between these 2 charges so you can expect to pay an amount between them.

Normative and positive statements.
deff fn [24]

Answer:

a. positive

b. normative

c. positive

d. normative

Explanation:

Note that a normative statement as used in economics refers to a view of what should be done, or how things or policies should be or not be. While the Positive statement gives a point blank description of what the state of things are.

a. It is a fact of course that in the past decades U.S. companies have outsourced millions of job overseas, thus this is a positive (descriptive) statement.

b. By saying companies that outsource jobs are acting immorally indicates a normative or judgemental view of what is morally right.

c. This statement is a fact, because such actions is in line with economic theory; in effect would stop outsourcing jobs.

d. This is rather a view of what should be done. Which clearly indicates the statement as normative.

Consider a hypothetical closed economy in which households spend $0.70 of each additional dollar they earn and save the remainin
MAVERICK [17]

(a) Marginal propensity to consume (MPC) = 0.7

(b) Multiplier of this economy:

     = 3.33

(c) Decrease government purchases by $300 billion,

Initial change in consumption = Change in government purchases × MPC

                                                 = $300 × 0.7

                                                 = -$210 billion

(d) This decreases income yet again, causing a second change in consumption equal to:

= Initial change in consumption × MPC

= -$210 × 0.7

= -$147 billion

(e) The total change in demand resulting from the initial change in government spending is:

= Change in government purchases × Multiplier

= $300 × 3.33

= -$1 trillion

Ostrovityanka [42]

Answer:

False

Explanation:

In a command or planned economy, the factors of production are owned and controlled by the government.  The government makes all the significant economic decisions such as production, distribution, and pricing.
