The Correct answer to this question for Penn Foster Students is: Direction
D is definitely the correct choice here.
I think a case could also be made for choice-B, but that would be a tough, complex operation.
Answer: option B
Explanation: The sampling error also known as the marginal error is given mathematically as
Margin of error = critical value × (standard deviation/√n)
Where n = sample size
As we can see from this formulae, the only variable here is the margin of error and the sample size.
Hence margin of error = k/√n
Which implies that there is an inverse relationship between margin of error and sample size.
A large sample size gives a low margin of error while a small sample size gives a large margin of error.
Answer:
Pressure = 1194.03 N/m
Explanation:
Given the following data;
Force = 800 N
Area = 0.67 m²
To find the pressure on your feet;
Mathematically, pressure is given by the formula;
Pressure = force/area
Pressure = 800/0.67
Pressure = 1194.03 N/m
