Problem 5 Answer: 
Answer:
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
Step-by-step explanation:
Confidence interval concepts:
A confidence interval has two bounds, a lower bound and an upper bound.
These bounds are dependent of the sample mean and of the margin of error.
The lower bound is the sample mean subtracted by the margin of error, while the upper bound is the margin of error added to the sample mean.
The confidence interval is likely to contain the true value of the population parameter.
In this question:
Sample mean: 48%
Margin of error: 4%
48 - 4 = 44%
48 + 4 = 52%
The range of values likely to contain the true value of the population parameter is between 44% and 52%.
In order to solve for this, we need to find the volumes of both the cylinder and cone described.
In order to find the area of the cylinder:
We use the equation V=

So, V=

The volume of the cylinder is therefore approximately <span>1809.56

For the cone:
V=

So, V=

Thus, the volume of the cone is 113.1

We add these volumes together to derive the solution, which is 1922.66
