Final answer:
The value of the sample proportion p^ varies from one random sample to another.
Step-by-step explanation:
The statement (a) True is correct. The value of the sample proportion p^ varies from one random sample to another. This is because the sample proportion is calculated based on the number of successes in the sample, and the sample size can differ between random samples. Therefore, the value of p^ can change depending on the specific sample taken.
