Final answer:
The sampling distribution of the proportion follows the normal distribution when the values np and nq are greater than or equal to 5.
Step-by-step explanation:
For the sampling distribution of the proportion to follow a normal distribution, the values np and nq must both be greater than or equal to 5.
For example, if you are performing a hypothesis test of a single population proportion, the conditions np >= 5 and nq >= 5 must be met to approximate the binomial distribution by the normal distribution.
Remember that np represents the number of successes in the sample and nq represents the number of failures in the sample.
