Competency

Formulate
and evaluate hypothesis tests for population parameters based on sample
statistics using both Critical Regions and P-Values, and be able to
state results in a non-technical way that can be understood by consumers
of the data instead of statisticians.

Dealing with Two Populations

Inferential
statistics involves forming conclusions about a population parameter.
We do so by constructing confidence intervals and testing claims about a
population mean and other statistics. Typically, these methods deal
with a sample from one population. We can extend the methods to
situations involving two populations (and there are many such
applications). This deliverable looks at two scenarios.

Concept being Studied

Your
focus is on hypothesis tests and confidence intervals for two
populations using two samples, some of which are independent and some of
which are dependent. These concepts are an extension of hypothesis
testing and confidence intervals which use statistics from one sample to
make conclusions about population parameters.
