The answer choice which is not a requirement for testing a claim about a population proportion is:

According to the given question, we are asked to select the answer choice from the available lists which is not a requirement for testing a claim about a population proportion.

As a result of this, we can see that a population proportion has to do with the fraction of a population which contains certain features and when making a test, the sample proportion (p) multiplied by the sample size must be greater than 5.

Therefore, the correct answer is option B

B. The conditions np ≥ 5 and nq ≤ 5 are both satisfied.

Explanation:

When testing a claim about a population proportion, all the other conditions must be satisfied except option B. This is because, the correct condition that should be satisfied is that np ≥ 5 and nq ≥ 5 which signifies that the sample proportion, p times the sample size is greater than 5 as well as 1-p which is q times the sample size is greater than 5 as well.

Option B is wrong because it says that nq has to be less than 5 when in fact it should be more.
