Answer:

[ $591.08, $1101.32 ]

Explanation:

Given:

Sample space = 200

Mean price = $846.20

Standard deviation, σ = $1,840.80

Confidence level = 95%

Now,

Confidence interval is given as:

⇒ Mean ± z\frac{\sigma}{\sqrt{n}}

here, z value for 95% is 1.96 from the standard z table

Thus,

Confidence interval

⇒ $846.20 ± 1.96\times\frac{\$1,840.80}{\sqrt{200}}

or

⇒ $846.20 ± 1.96\times\frac{\$1,840.80}{\sqrt{200}}

or

⇒ $846.20 ± 255.12

or

⇒ [ $846.20 - 255.12, $846.20 + 255.12 ]

or

⇒  [ $846.20 - 255.12, $846.20 + 255.12 ]

or

⇒ [ $591.08, $1101.32 ]

topjm [15]

Answer: Option (d) is correct.

Explanation:

Correct option: Market price is greater than marginal cost.

In a perfectly competitive market, there are large number of buyers and sellers. So, price is determined by the market forces.

At a point of profit maximization, price is equal to the marginal cost and we have to maximize the difference of the total revenue and total cost. It was not seen in a perfectly competitive market that the price is above the marginal cost at a profit maximizing point.

Therefore, option (d) is not true.

Eduardwww [97]

Answer:

a. a grant will be secured to help fund the project.

Explanation:

In project management, a project manager can be defined as an individual or organization that temporarily undertakes a project in order to create a unique result, product, and service. Project managers strives very hard so that they can achieve their aims, goals and objectives in the most cost-effective, efficient and best manner through the use of unique set of interrelated tools, skills and tasks.

An assumption for a construction project could be, a grant will be secured to help fund the project.

Project managers sometimes embark on the execution of projects without having enough fund to finish it successfully. There assumptions are usually that once they have commenced the process, a grant can be secured from creditors, investors or financial institutions to help fund the remaining part of the project. However, since it is an assumption, they're not guaranteed that the grant will be given to them; therefore, this can result to the stalling of projects sometimes.

By virtue of standards, materials to be used to construct the building, the size of the building that is to be constructed and the regulations and codes required for the building should never be assumed by project managers.
