Inference app
The Inference app can calculate confidence intervals and
test hypotheses based on data in the Statistics 1Var and
Statistics 2Var apps. The following example illustrates the
process.
A series of six experiments gives the following values as
the boiling point of a liquid:
82.5, 83.1, 82.6, 83.7, 82.4, and 83.0
Based on this sample, we want to estimate the true boiling
point at the 90% confidence level.
1. Open the Statistics
1Var app:
