Using the Central Limit Theorem, it is found that each random sample must have at least 10 parents supporting the change and 10 opposing.
<h3>What does the Central Limit Theorem state?</h3>It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportion is approximately normal with mean and standard deviation
, as long as
and
.
For the test hpyothesis, two conditions are needed:
- Random samples.
- The sampling distribution must be approximately normal.
Hence each random sample must have at least 10 parents supporting the change and 10 opposing.
