Explanation:
Detailed explanation-1: -Question: A recent survey finds that 35% of US households have at least one dog. You randomly choose 50 households to ask if they have a dog. Could you use the Normal Approximation for this? Yes.
Detailed explanation-2: -The central limit theorem states that if you have a population with mean and standard deviation and take sufficiently large random samples from the population with replacement, then the distribution of the sample means will be approximately normally distributed.
Detailed explanation-3: -A sampling distribution is a distribution where we take ALL possible samples of a given size and put those sample statistics together as a data set.
