  4. The Sampling Distribution of the Sample Proportion The sampling distribution of the sample proportion is the probability distribution of all possible values of the sample proportion,, when a sample of size n is taken from a particular population.

  5. Standard Deviation of the Sampling (8.1) Distribution of the Sample Proportion

  10. The Sampling Distribution of the Sample Mean Difference The sampling distribution of the sample mean difference is the probability distribution of all possible values of the sample mean difference, - , when a sample of size n1 is taken from one population and a sample of size n2 is taken from another.

  16. Estimating the Difference between (8.9) Means of Two Populations:Small Sample Sizes, Population Standard Deviations are Unknown but equal

  17. The Sampling Distribution of the Sample Proportion Difference The sampling distribution of the sample proportion difference is the probability distribution of all possible values of the sample proportion difference, - , when a sample of size n1 is taken from one population and a sample of size n2 is taken from another.
