Homework Help: sample size/ standard deviations

Posted by ut on Thursday, December 1, 2011 at 10:15am.

How do we compute sample size fluctuations? Suppose we have a population of 16000 and a sample size of 30, and the number of samples 1000, what will be the impact on population mean and standard deviation when the population is normally distributed? When the population is skewed? And when the population shows uniform distribution what will happen to the standard deviation and mean (increase/decrease)?
