To produce good estimates of population parameters, we need to have a random sample. This is because a random sample ensures that every member of the population has an equal chance of being selected, which reduces the risk of bias and improves the representativeness of the sample. A normal sample is not necessary for estimating population parameters, and an independent or systematic sample may introduce bias into the sample selection process.
