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:
0.4766
Explanation:
Given:
WACC = 9.7%
Company’s cost of equity = 12%
Pretax cost of debt = 7.5%
Tax rate = 35%
Now,
WACC
= Weight × Cost of equity + (1 - weight) × Pretax cost of debt × (1-tax rate)
or
0.097 = weight × 0.12 + ( 1 - weight ) × 0.075 × (1 - 0.35)
or
0.097 = 0.12 × weight + 0.04875 - 0.04875 × weight
or
0.04825 = 0.07125 × weight
or
weight = 0.6772
also,
weight = 
or
= 
or
= 
+ 1
or
1.4766 = + 1
or
= 0.4766
Answer:
Explanation:
First, convert the basis points to a percentage or decimal;
1 basis point = 0.01% or 0.0001 as a decimal
Then 443 basis points as a decimal will be;
443 *0.0001 = 0.0443 or 4.43% as a percentage
Next, since the BB bond is 4.43% above the U.S. Treasury yield of 2.76%, find the Yield to maturity(YTM) by adding the 4.43% to the 2.76%;
YTM = 2.76% + 4.43%
YTM = 7.19%
