Answer:
a. a parameter.
Step-by-step explanation:
A parameter is a property that describes the whole population, while a statistic is a property pertaining to a sample or sub-set of the population.
In this example, the average content of 4 ounces pertains to the 121 bottles sample and thus is a statistic. While the standard deviation of the population is mentioned to be 0.22 ounces, therefore 0.22 is a parameter.
<u>Given</u>:
Let x represents the radius of the cylinder.
Given that the height of the cylinder is twice the radius of its base.
The height of the cylinder is 2x.
We need to determine the volume of the cylinder.
<u>Volume of the cylinder:</u>
The volume of the cylinder can be determined using the formula,

Substituting r = x and h = 2x, we get;

Simplifying, we get;


Thus, the expression that represents the volume of the cylinder is 2πx³ cubic units.
