<h3>What is statistical inference?</h3>
statistical inference uses sample data to make estimates of or draw conclusions about one or more characteristics of a population.
The purpose of statistical inference is to estimate this sample to sample variation or uncertainty. Understanding how much our results may differ if we did the study again, or how uncertain our findings are, allows us to take this uncertainty into account when drawing conclusions. It allows us to provide a plausible range of values for the true value of something in the population, such as the mean, or size of an effect, and it allows us to make statements about whether our study provides evidence to reject a hypothesis.
We have four ideas for using the statistical inference.
1. Estimating uncertainty.
2. Confidence intervals.
3. Hypothesis tests.
4. Connections with other material.

Answer:
Inconsistent
Step-by-step explanation:
We are given the equations;
0.3y=0.6x+0.3
1.2x+0.6=0.6y
Assuming we are required to determine whether the system of equations are consistent or inconsistent
We are going to use substitution
Making y the subject;
Equation 1: 0.3y=0.6x+0.3
Dividing both sides by 0.3
y = 2x + 1
Equation 2: 1.2x+0.6=0.6y
Dividing both sides by 0.6
y = 2x + 1
This means both equations are similar and we can't get a solution.
Therefore, the system of equations is inconsistent.
F(2) = 8
if x = 2 then you plug in 2 for x making the equation 3(2) + 2 which equals 8
