Inference app 241
Importing statistics
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.
