As a rule of thumb, the sampling distribution of the sample proportion can be approximated by a normal probability distribution whenever the sample size is large.
<h3>What is the Central limit theorem?</h3>
- The Central limit theorem says that the normal probability distribution is used to approximate the sampling distribution of the sample proportions and sample means whenever the sample size is large.
- Approximation of the distribution occurs when the sample size is greater than or equal to 30 and n(1 - p) ≥ 5.
Thus, as a rule of thumb, the sampling distribution of the sample proportions can be approximated by a normal probability distribution when the sample size is large and each element is selected independently from the same population.

Answer:
1 solution (x = 1.5)
Step-by-step explanation:
2x + 2 - 3x = 3x - 4
First, combine like terms
2 - x = 3x - 4
Add 4 to both sides
6 - x = 3x
Add x to both sides
6 = 4x
Divide both sides by 4
1.5 = x
