7 0

Answer:

± 4.05

Explanation:

Data provided in the question:

Random sample size = 15

Standard deviation = 8

Confidence level = 95%

Now,

Margin of error is given as:

Margin of error = ± [ ( z × s ) ÷ √n ]

Here,

From standard z table for 95% confidence level z = 1.96

Margin of error = ± [ ( 1.96 × 8 ) ÷ √15 ]

or

Margin of error = ± [ 15.68 ÷ 3.873 ]

or

Margin of error = ± 4.05

adelina 88 [10]

If there is an increase in labor productivity, there will be an <u>increase </u>in wages and an <u>increase </u>in individuals employed.

If better insurance policies are mandated by the government then wages and the number of people employed will <u>both decrease</u>.

This shows that the entity that actually pays the costs of health insurance premiums is <u>employers</u>.

<h3>What happens when labor productivity rises?</h3>

When there is an increase in labor productivity, employers will demand more employees in order to produce more. This will shift the labor demand curve to the right.

The new intersection of the demand curve with the supply curve will see an increase in the wage rate and in the quantity of those employed in the labor market.

<h3>What happens if better insurance policies are imposed?</h3>

If the government mandates that employers should provide better insurance policies, it means that employers will start paying more in insurance premium contributions.

This increased cost of labor will lead to employers demanding less employees which will lead to a decrease in the wage rate and in the number of those employed.

This shows that employers are mostly the ones who pay for health insurance premiums which is why an increase in these premiums will increase the cost of labor for them.

tigry1 [53]

Answer:

The correct answer is d. marginal cost of abatement is the same across all polluters.

Explanation:

According to the pollution economy, the marginal cost of reduction refers to the distribution made to determine the level of impact that falls on the environment and that is taken into account as an incentive for the reduction of polluting emissions. For this calculation, all pollutants are considered to have the same impact, which suggests that for the pollution economy there is no different determination to calculate the marginal cost of the impact.
