Sources of error refer to problems in sampling that reduce the ability to make accurate deductions about the population as a whole. Examples of sources of error are:
<u>Non observation errors:</u> choosing a bad sample, not getting a high response from the sample that you do choose, etc
<u>Observation errors:</u> respondent and interviewer bias
<u>Processing errors:</u> incorrectly organizing or categorizing the data
Answer:
The answer is: Duncan's materials costs per unit was $1.50 ($6.10 - $4.60) less than Davis's materials costs per unit.
Explanation:
We must first calculate the materials costs for both companies:
- Duncan's total costs was $457,250 minus conversion costs of $279,000 equals total materials costs of $178,250.
-
Davis's total costs was $721,056 minus conversion costs of $381,408 equals total materials costs of $339,648
.
Now we calculate the materials costs per unit produced:
- Duncan's total materials costs $178,250 divided by 38,750 units equals $4.60 per unit.
- Davis's total materials costs $339,648 divided by 55,680 units equals $6.10 per unit.
So Duncan's materials costs per unit was $1.50 ($6.10 - $4.60) less than Davis's materials costs per unit.

Answer:
Beta= 1.17
Explanation:
Giving the following information:
Shirley Paul's 2-stock portfolio has a total value of $100,000. $37,500 is invested in Stock A with a beta of 0.75 and the remainder is invested in Stock B with a beta of 1.42.
To calculate the Beta of the portfolio, we need to use the following formula:
Beta= (proportion of investment A*beta A) + (proportion of investment B*beta B)
Beta= (37,500/100,000)*0.75 + (62,500/100,000)*1.42
Beta= 1.17
Answer:
total interest = $1125
Explanation:
given data
principal = $27,000
rate = 5 %
time = 10 months
to find out
total interest
solution
we get here total interest that is express as
total interest = principal × rate × time ....................1
put here value and we get
total interest = $27,000 × 5 % × 
total interest = $1125
True because heat breaks down the molecular structure and pressure reinforced the new contiguous configuration
