The Inference capabilities include calculation of
confidence intervals and hypothesis tests based on the
Normal Z-distribution or Student's t-distribution.
Based on the statistics from one or two samples, you can
test hypotheses and find confidence intervals for the
following quantities:
• mean
• proportion
• difference between two means
• difference between two proportions
When you first access an input form for an Inference test,
by default, the input form contains example data. This
example data is designed to return meaningful results that
relate to the test. It is useful for gaining an understanding
of what the test does, and for demonstrating the test. The
calculator's on-line help provides a description of what
the example data represents.
This example describes the Inference aplet's options and
functionality by stepping you through an example using
the example data for the Z-Test on 1 mean.
