Answer: comparison postulate.
Justification.
Although the comparison sign of the inequality is missing, the answer may be perfectly reasoned and properly answered.
The inequality might be either 3 + 2 > 5 or 2 + 2 < 5, in either case the answer is the same.
The comparison postulate states that one and only one of the following statements is true: x = y, x > y, y < x.
This is, x is either equal, or greater than or less than y, but not equal and greater, or equal and less, or greater and less. One and only one of them is true.
So, if 3 + 2 = 5, the comparison postulate assures that it cannot be true both the equality and the inequality.
Using the z-distribution, it is found that a sample size of 3,385 is required.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
The margin of error is:
In which:
- is the sample proportion.
In this problem, we have a 98% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 2.327.
We have no prior estimate, hence is used, which is when the largest sample size is needed. To find the sample size, we solve the margin of error expression for n when M = 0.02, hence:
n = 3,385.
A sample size of 3,385 is required.
