Horizontal axes are presented for both the distribution variable and the test statistic. A generic

bell curve represents the probability distribution function. Vertical lines mark the critical value(s) of the test, as well as the value of the test statistic. The rejection region is marked R and the test numeric results are displayed between the horizontal axes.

Importing Sample Statistics from the Statistics aplet

Open the Statistics aplet

The Inference aplet supports the calculation of confidence intervals and the testing of hypotheses based on data in the Statistics aplet. Computed statistics for a sample of data in a column in any Statistics-based aplet can be imported for use in the Inference aplet. 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

1.Open Statistics aplet. Note: Reset current settings.
