Parametric tests:

True / False

Are less powerful than non-parametric ones Correct

Include analysis of variance Correct

Require the data to have a normal distribution Correct

Are appropriate for comparing the incidence of hypotension in two groups Correct

Give the results as odds ratios Correct

Explanation

Whereas non-parametric tests could be used for normal or non-normal data.

Parametric tests give a p value.

The incidence of hypotension, i.e. it did/did not occur, would be categorical (or qualitative) data thus requiring a non-parametric test, e.g Chi squared test. They are more powerful, i.e. they are more likely to show a difference that really exists.

Analysis of variance (ANOVA) is used for testing multiple groups of parametric data.
