Answer:

A. Observational study

Explanation:

An observational study measures the characteristics of a population by studying individuals in a sample, but does not attempt to manipulate or influence the variables of interest.

A designed experiment applies a treatment to individuals (referred to as experimental units or subjects) and attempts to isolate the effects of the treatment on a response variable.

Hence, we can see that proposed study is observational.

solong [7]

Correct answer choice is:

D. Accident investigation.

When conflicts are reviewed, the importance should be focused on determining the root reason of the occurrence so you can block the event from occurring again. The goal is to find evidence that can direct to remedial activities, not to determine responsibility. Constantly look for distant causes.

You are the manager of College Computers, a manufacturer of customized computers that meet the specifications required by the lo
sertanlavr [38]

The price and quantity of computers that should be produced to maximize the firm’s profits will be $360 and 80 computers.

The demand curve for College Computers is given as (Q) = 800 - 2P where, P = 400 - 0.5Q.

Therefore, the weekly total revenue will be:

= (400 - 0.5Q) × Q

= 400Q - 05Q²

Marginal revenue = 400 - Q

Weekly cost of producing computers will be:

= 1200 + 2Q²

Marginal cost = 4Q

Maximum profit will b earned when MR = MC

Therefore, 400 - Q = 4Q

Collect like terms

4Q + Q = 400

5Q = 400

Q = 400/5

Q = 80

Quantity = 80 units

Therefore, the price will be:

P = 400 - 0.5Q

P = 400 - 0.5(80)

P = 400 - 40.

P = 360

The price is $360.

The weekly total revenue will be:

TR = price × quantity.

TR = 360 × 80

TR = $28800

The total cost will be:

TC = 1200 + 2(80)²

TC = 1200 + 12800

TC = 14000

Therefore, the profit will be:

= TR - TC

= $28800 - $14000

= $14800
