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.

borishaifa [10]

Answer and Explanation:

The computation of the variable cost per unit and the total fixed cost is shown below;

a. The variable cost per unit is

= ($440,000 - $300,000) ÷ (5,500 - 2,700)

= $140,000 ÷ 2,800

= $50

b. The total fixed cost is

= $440,000 - 5,500 × $50

= $440,000 - $275,000
