The graph of the
distribution is displayed,
with the test Z-value marked. The corresponding X-
value is also shown, as well as the critical Z-value.
Press the

menu key to see the critical Z-value as
well. With the menu key active, you can use the
left- and right-cursor keys to decrease and increase

Importing sample statistics
The Inference app supports the calculation of confidence
intervals and the testing of hypotheses based on data in
the Statistics 1Var and Statistics 2Var apps. Computed
statistics for a sample of data in a column in any Statistics-
based app can be imported for use in the Inference app.
The following example illustrates the process.
A calculator produces the following 6 random numbers:
0.529, 0.295, 0.952, 0.259, 0.925, and 0.592
