Answer:  To remove bias when estimating the proportion of working adults living in urban, suburban, and rural areas.

Explanation: In simple words, stratification refers to the process in which different sections of the society are grouped on the basis of one or more general factors.

In the given case, the company wants to estimate the minutes of working adults in the region and the region is grouped into urban, suburban and rural.

Thus, the random selection from different regions is done so that no bias takes place regarding the number of adult working in these three different areas.

Answer:

Profit from sale of special order = $77,900 - $33,610 = $44,290

Explanation:

Being a special order and an added opportunity to its regular sales of S47, we will be looking at the Marginal Costs of accepting to produce the order:

Direct Material = $4.30

Direct Labour = $4.00

Variable Overhead = $3.60

Fixed Manufacturing Overhead = $6.30

Total Costs = $18.20

But, Fixed Costs is already covered/absorbed by our existing business; as such we need not include it in the costing of the special order

And there is an Additional investment in moulds = $11,000

Total cost of special order = ($18.20 - $6.30) x 1,900 units + $11,000

= $33,610

Sales of special order = 1,900 units x $41 =$77,900

Profit from sale of special order = $77,900 - $33,610 = $44,290
