Parametric tests:

True / False

Are appropriate for comparing the incidence of hypertension in two groups Incorrect answer selected

Are less powerful than non-parametric tests Correct

Give the results as odds ratios Correct

Include the analysis of variance Correct

Require the data to have a normal distribution Correct

Explanation

The incidence of hypertension, that is, did/did not occur, would be categorical (or qualitative) data thus requiring a non-parametric test (that is, chi square test).

They are more powerful than non-parametric tests, that is, they are more likely to show a difference that really exists.

Parametric tests give p values and not odds ratios.

Analysis of variance (ANOVA) is used to test multiple groups of parametric data.

Parametric tests require the data to have a normal distribution, whereas non-parametric tests could be used for normal and non-normal data.
