As the SD increases, the exactness of the estimate of a population mean is less.

The null hypothesis usually assumes a normal distribution. As I mentioned in your later post, assu7ming that the distribution isdue to chance factors, the sampling distribution will approximate a normal distribution more closely as the sample size increases.

I hope this helps a little more. Thanks for asking.
