Sampling Distribution Worksheet

Use this worksheet to study the effect of sample size on the shape of the sampling distribution. As you adjust the sample size n, note how the standard error of the mean changes, and thus how the shape of the sampling distribution changes.

How does the probability P(23 < x-bar < 25) change as n increases? Does it increase or decrease?
How does the probability P(26 < x-bar < 27) change as n increases? Does it increase or decrease?
Will large samples have more variability or less variability in sample means than small samples ?
