Sampling Distributions Given a sampling distribution of means, how are the mean and standard deviation determined (calculated)? If an original sampling is not normal, how many must we sample to say it is approximately normal? Given a sampling distribution of proportions, how are the mean and standard deviation determined (calculated)?
The distribution of sample means has the same mean as the underlying population, but the standard...
The distribution of sample means has the same mean as the underlying population, but the standard deviation differs. Use a real world scenario to explain why it makes sense the variation decreases as the sample size increases.

The two curves below represent the sampling distribution of the sample mean X for two different sample sizes: n = 256 and n = 576. In both cases the samples are selected from the same population. Note that the standard deviation for sampling distribution A is SD(X) = 8 and for sampling distribution B the standard deviation is SD(X) = 12. What is the standard deviation SD(X) of the population from which the samples are taken? A-8^2 B-(12+8)/2 C-13.86 D-12^2...
