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

Open the Statistics 1Var app

Clear unwanted data

Enter data

Based on this sample, we want to estimate the true boiling point at the 90% confidence level.

1.Open the Statistics 1Var app:

ISelect

Statistics 1Var

2.If there is unwanted data in the app, clear it: SJAll columns

3.In column D1, enter the boiling points found during the experiments.

82.5 E

83.1 E

82.6 E

83.7 E

82.4 E
