The Central Limit Theorem predicts that, particularly, for larger sample sizes, the probability distribution of the sample means will approximate a normal distribution no matter the shape of the underlying distribution. Does this data bear this out? Explain why or why not.#| [Type Answer Here] 2. Statistics also predicts that, as the number of trials increases, the mean of the sampling distribution of sample means approaches the mean of the original population. Does this data bear this out? Explain why or why not. [Type Answer Here] 3. Statistics also predicts that, as the number of trials increases, the standard deviation of the sampling distribution of sample means approaches the square root of the original population divided by the square root of the sample size. Does this data bear this out? Explain why or why not. [Type Answer, Here]
