Inference app’s Symbolic view options
The table below summarizes the options available in
Symbolic view.
If you choose one of the hypothesis tests, you can choose
the alternative hypothesis to test against the null
hypothesis. For each test, there are three possible choices
for an alternative hypothesis based on a quantitative
comparison of two quantities. The null hypothesis is
always that the two quantities are equal. Thus, the
alternative hypotheses cover the various cases for the two
quantities being unequal: <, >, and
≠
.
