What is hypothesis in Minitab?

A hypothesis test examines two opposing hypotheses about a population: the null hypothesis and the alternative hypothesis.

How do you test a questionnaire with a hypothesis?

When you use sample data to test a hypothesis, the analysis includes the same seven steps:

1. Estimate a population parameter.
2. Estimate population variance.
3. Compute standard error.
