In each case, find the approximate sample size required to construct a 95 % confidence interval for p that has sampling error SE=.06 a. Assume that p is near .3. b. Assume that you have no prior knowledge about p, but you wish to be certain that your sample is large enough to achieve the specified accuracy for the estimate. | Numerade

Artificial Intelligence | AI on Instagram: "The Central Limit Theorem (CLT) is a foundational statistical principle stating that the distribution made from sampling independent, identically distributed random variables will converge to a normal distribution as the sample size increases, regardless of the original population’s distribution. We can visualize this using the ball and peg example in the video. As we draw random variables (the ball’s final position), we notice that they slowly, over t
