Because only young adults were sampled, undercoverage bias may cause the newspaper to overestimate the proportion of all adults who have college debts.
<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.

Answer:
The correct answer is (A)
Explanation:
The cost which is directly associated with converting materials into a finished product is known as direct labour cost. The cost of wages paid to employees is the direct cost involved in the manufacturing process. In other words, a cost that is directly involved in the production of goods and services is the direct cost, for example, direct cost, direct commission, direct material cost.
Answer:
1.90
Explanation:
Calculation for how many cells that the company require to satisfy predicted demand
Using this formula
Numbers of cell=Projected annual demand/Annual capacity per cell
Based on the information given we were told that Annual demand is 50,000 units in which it is forecasted that within 2 years it will tripple which means that Annual demand will be calculated as:
Projected annual demand = 50,000*2 years
Projected annual demand=100,000
Let plug in the formula
Numbers of cell=100,000÷(220 units/day × 238 days/year)
Numbers of cell=100,000÷52,360
Numbers of cell=1.90
Therefore the amount of cells that the company require to satisfy predicted demand will be 1.90
Answer:
a. Project A requires an up-front expenditure of $1,000,000 and generates a net present value of $3,200.
Explanation:
a.
The company should accept project A because it provides a positive net present value of $3,200 that is the highest among all the projects.
b.
When the IRR of a project is lower than the required rate of return of the project, it will generate the negative net present value because at IRR the net present value of the project will be zero and at a higher rate than IRR it will be negative.
c.
The project with a profitability index of less than 1 generates a negative NPV because the present value of future cash flows is less than the initial cash outflow.
d.
Project D also generates a positive net present value but it is lower than project A. So, after comparing the results we will choose the project with higher NPV.
