Answer the following Questions:

1. How do you calculate the mean and standard deviation of the sampling distribution for sample means? [2 to 3 sentences]

2. What is the effect of increasing sample size on the sampling distribution and what does this mean in terms of the central limit theorem? [2 to 3 sentences]

3. Why is the standard deviation of the sampling distribution smaller than the standard deviation of the population from which it came? [3 to 4 sentences]

NOTE: Answers to the above questions should be answered generally - not in respect to the video.  The video is to give you a better understanding of sampling distributions and the CLT.
