What's Cool about the QI Macros One Sample Hypothesized Variance Test?

Interprets the Results for You: QI Macros compares the p value to alpha and tells you what that means. In the above example, QI Macros tells you "Cannot Reject the Null Hypothesis/Accept the Null Hypothesis," because p > 0.05 (Means are not different/Means are the same).

Interactive Results: QI Macros lets you change the significance level to see what impact those changes have on your results.
