Two probability distributions that help us assess how accurate the sample mean and sample proportion are likely to be as point estimates are the sampling distribution of sample mean and the sampling distribution of the sample proportion.

Initial Post Instructions

• Under what condition may we use the normal approximation to the binomial distribution?
• What two properties must be satisfied by a continuous probability distribution (or probability curve)?
• Explain why sampling without replacement is preferred to sampling with replacement
• What does the Central Limit Theorem tell us about the sampling distribution of the sample mean?
