Answer:

A. The number of houses that an individual owns

Explanation:

The use of normal distribution in option A would produce an error. That is the number of houses individuals own.

We know that people can own 1 house or more than 1 house or no house at all. But a person can never be said to have less than 0 houses.

Option a is going to be skewed positively. Using Normal distribution would give us an error.

koban [17]

Answer:

$9,000 (amount invested at 3.8%)

$11,000 (amount invested at 8.1%)

Explanation:

Let us calculate the total interest earned by both investments

Interest earned= 0.06165* 20,000= $ 1,233

Let principal invested at 3.8% be X

Use formula Interest= principal* rate*time in years

Interest= X*0.038*1= 0.038X

Principal invested at 8.1% be (20,000-X)

So Interest = (20,000-X)*0.081*1= 1,620-0.081X

Total interest earned = Interest at 3.8% + Interest at 8.1%

1,233= 0.038X + 1,620 -0.081X

Rearranging

0.043X= 387

X= 387/0.043

X= $9,000 (amount invested at 3.8%)

Substitute in equation

Principal invested at 8.1%= 20,000-X

= 20,000- 9,000

= $11,000 (amount invested at 8.1%)

Answer:

much more likely;

There is only one car dealership in a small town, giving the dealership the ability to influence the price of cars. - Market power

A person smoking in a restaurant emits second-hand smoke that harms other restaurant patrons. - Externality

Explanation:

Property rights are an incentive for individuals to create goods that are needed on the market. In other words, when a discrepancy between demand and supply occurs on a specific market, entities, businesses or individuals that create the goods are motivated to meet market needs through enforced property rights.

On the other hand, when there is a lack of property rights that regulate the market, market failures occur. Two common types of market failures include market power and externalities.

The car dealership example shows market power in practice, as the reigning company can dictate car prices.

The second example shows an externality, as there is evident influence (cost or benefit) on the third party, which they cannot change. People are affected (negatively) by smoke they did not create.
