Inference app
The Inference app enables you to calculate confidence
intervals and undertake hypothesis tests based on the
Normal Z-distribution or Student's t-distribution.
Based on statistics from one or two samples, you can test
hypotheses and find confidence intervals for the following
quantities:
mean
•
proportion
•
difference between two means
•
difference between two proportions
•
The Inference app comes with sample data (which you
can always restore by resetting the app). This sample data
is useful in helping you gain an understanding app. The
calculator's on-line help provides a description of what the
sample data represents.
Let's conduct a Z-Test on one mean using the sample data.
