... If samples were related in some way (e.g., brothers vs. their sisters, husbands versus wives, pretest vs. posttest), we would be using dependent samples. We will return to this topic later. In the very rare circumstance that we know both population standard deviations but do not know the population ...

B) 10% condition: The sample is less than 10% of the population. 2. Normal Population Assumption: the underlying populations are each Normally distributed ...

... Part B: Exploring the Sampling Distribution of the Sample Mean 1. Simulation. (Use the same applet as in part A.) For each parent distribution and sample size given on the table that follows, write down the mean and the standard deviation (given by the computer) in the first column. Then, compute t ...
