Determine whether the study depicts an observational study or a designed experiment. A researcher obtained a random sample of 10

Anastasy [175]

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.

The theory of comparative advantage states that there are gains from trade if countries specialize and optimize their opportunit

Margarita [4]

In simpler terms, the theory of comparative advantage refers to the possibility of one given economic actor to produce the same good which is of the same size and quality. This becomes a force behind trade because there are specific materials that are found in specific area in the Philippines only.

Doing trading is I think is better than being self-sufficient .

Answer:

Month Maintenance Machine Equation MAPE

costs hours error (Abs.)

1 $2,750 1,840 $269 9.78%

2 $2,910 1,920 $197 6.77%

3 $3,060 2,000 $135 4.41%

4 $3,170 2,020 $47 1.48%

5 $3,250 2,050 0 0%

6 $3,220 2,030 $8 0.25%

7 $3,160 2,010 $46 1.46%

8 $3,000 1,990 $184 6.13%

9 $2,770 1,850 $260 9.39%

10 $2,370 1,250 0 0%

11 $2,380 1,450 $210 8.82%

12 $2,600 1,740 $309 11.88%

60.37%

variable cost per unit = (highest activity cost - lowest activity cost) / (highest activity units - lowest activity units) = ($3,250 - $2,370) / (2,050 - 1,250) = $880 / 800 units = $1.10 per unit

fixed cost = $3,250 – ($1.10 x 2,050) = $995

Cost model = $995 + $1.10X

2. Calculate the mean absolute percentage error (MAPE) for the cost equation you developed in requirement 1.

MAPE = 60.37% / 12 = 5.03%

Clayton, a supervisor, needs to rate the performance of 20 subordinates. he uses a rating scale to rate them on a scale of 1 to

Masteriza [31]

The answer is a distributional error. Raters make distributional blunders when they tend to utilize just a single piece of a rating scale. Distributional blunders make it hard to look at representatives appraised by a similar individual. The mistake is called focal inclination when the rater puts everybody close to the center of the scale. In this situation, Clayton submits a distributional mistake.
