Mary begins an internship at a small company that makes touchscreens for imported smartphones. Her first assignment is to estima

te the probability of rejecting a randomly sampled box of eight flat screens. But her boss explains that there are two complications. The first is that the contract between the company and the importer demands that she inspect exactly two screens per box of eight and then that she accept the box only if both screens are not defective. The second is that 60% of the boxes have only one defective screen in them while 40% of the boxes have three defective screens in them. Mary’s boss wants to know if this means that more than half the boxes will be rejected. How should Mary answer?

Answer:

Mary should answer that more than half of the boxes not be rejected.

Explanation:

Probability:

Box has one defective screen = 0.6

Box has three defective screen = 0.4

no. of screens in a box = 8

The box is rejected if both of the inspected screens are defective.

Probability of rejecting a box:

=0.6\times\frac{1}{8}\times\frac{0}{7} + 0.4\times\frac{3}{8}\times\frac{2}{7}

= 0.04286

Only 4.286% of the boxes will be rejected.

Therefore, Mary should answer that more than half of the boxes not be rejected.

If gas prices fell sharply, what would economists expect to happen in the market for fuel-efficient hybrid cars?
Thepotemich [5.8K]

Answer:

The correct answer is:  a decrease in the price and quantity of hybrid cars.

Explanation:

According to the Efficient Market Hypothesis (EMH), publicly-available information influence the asset's price movement. In that sense, if it is widely known that the gas prices will fall sharply, hybrid cars -fuel and electrical fueled cars, will see a fall in their price since the demand will increase. As implies fewer profits for a company, they are likely to produce fewer units of those types of vehicles.

Suppose that an initial $10 billion increase in investment spending expands GDP by $10 billion in the first round of the multipl
Fynjy0 [20]

Answer:

If GDP and consumption both rise by $6 billion in the second round of the process, what is the MPC in this economy?

  • MPC = 0.8

What is the size of the multiplier?

  • multiplier = 2.5

If, instead, GDP and consumption both rose by $8 billion in the second round, what would have been the size of the multiplier?

  • multiplier = 5

Explanation:

Since the change in consumption is $6 billion, and the initial expansion in investment was $10 billion, the marginal propensity to consume (MPC) = expansion in consumption / initial expansion = $6 / $10 = 0.6

the economy's multiplier = 1 / (1 - MPC) = 1 / (1 - 0.6) = 1 / 0.4 = 2.5

If both the economy and the GPD had expanded by $8 billion, the MPC = $8 / $10 = 0.8, so the economy's multiplier = 1 / (1 - 0.8) = 1 / 0.2 = 5

Another way to determine the multiplier = 1 / MPS (marginal propensity to save), since MPS = 1 - MPC
