The volume of the base of the region enclosed by the parabola is; V = 9
<h3>Integral Volume of a Solid</h3>
The length of each cross-section is determined by the horizontal distance (parallel to the x-axis) from one end of the parabola to the other.
Thus;
y = 3 - 2x²
Making x the subject gives us;
x = ±√[(3 - y)/2]
Thus;
The horizontal distance is;
√[(3 - y)/2] - (-√[(3 - y)/2])
⇒ 2√[(3 - y)/2]
The area of each cross-section is simply the square of the section's side length, so the area would be;
A = (2√[(3 - y)/2])²
A = 6 - 2y
Thus, volume is;
V = 
Solving this gives V = 9

Explanation:
The degrees of freedom can be used to test a hypothesis about the mean.
<h3>What is degrees of freedom?</h3>
Degrees of freedom refers to the maximum number of logically independent values that have the freedom to vary, in the data sample.
Given, the sample size is 20, then degree of freedom will be
The degrees of freedom represented as
dof = n – 1
dof = 20 – 1
dof = 19
Thus, the degrees of freedom can be used to test a hypothesis about the mean.
