<h3><u>What is bias in sampling?</u></h3>
When a sample is chosen in statistics, sampling bias is a bias that causes some individuals of the target population to have a lower or greater sampling probability than others. As a result, not every person or event was equally likely to have been chosen, resulting in a biased sample of a population (or non-human variables).
If this is not taken into consideration, results may be incorrectly attributed to the sampling procedure rather than the phenomenon being studied. Although some people identify sampling bias as a distinct sort of prejudice, sampling bias is typically categorized as a subtype of selection bias, sometimes referred to as sample selection bias.

Explanation:
By definition marginal revenue is the revenue generated by the sale of one more unit of product Z.
Marginal revenue = unit price
Since firm X participates in a perfectly competitive market, it is a price taker, and since the marginal revenue is constant, we can assume that this is the equilibrium price of product Z.
Answer:
the cash payback period is 6.09 years
Explanation:
The computation of the cash payback period is shown below:
= Initial Investment ÷ Net annual cash inflow
= $1,400,000 ÷ $230,000
= 6.09
Now the net annual cash flow is
.
Net operating income $90,000.00
Add: Depreciation $140,000.00
Net annual cash inflow $230,000.00
Hence, the cash payback period is 6.09 years
Answer:
a. both the cost of the goods sold and the cost of ending inventory.
Explanation:
The physical count is used in the periodic inventory system to calculate the amount of ending inventory. However the cost of goods sold can be derived from using the ending inventory count. Suppose we have ending inventory of 100 units and Purchases were 500 units Also there were no beginning inventory units so the Cost of goods Sold can be calculated as
Cost of Goods Sold= Beginning Inventory Add Purchases Less Ending Inventory
Cost of Goods Sold= 0 + 500- 100= 400
