Which of the following statements about the Central Limit Theorem is/are TRUE?A. From a given population that is not normally distributed, the distribution of the sample means approaches anormal distribution as the sample size n increases.B. When a random variable X has a normal distribution, the distribution of the sample means will also benormal for any sample size n.O A onlyO B onlyO Neither A nor BO Both A and B Which of the following is false about estimation?O The objective of estimation is to approximate the value of a population parameter using a statistic.O The endpoints of a confidence interval estimate are the best point estimates of the parameter.O The z-score associated with 98% confidence level is 2.33.O An interval estimator with 95% confidence means that if multiple samples of the same size are taken from the population,about 95% of these samples will be intervals that capture the actual population parameter.
