Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Parametric tests make assumptions about population parameters or distribution, usually involving mean, variance or proportion.
Step 1: Check ANOVA.
ANOVA is a parametric test. \[ A \text{ is correct} \]
Step 2: Check \(t\)-test and \(z\)-test.
Both \(t\)-test and \(z\)-test are parametric tests. \[ B \text{ and } C \text{ are correct} \]
Step 3: Check proportion test.
Proportion test is also treated as a parametric test. \[ D \text{ is correct} \]
Step 4: Check Wilcoxon's test.
Wilcoxon's test is a non-parametric test. \[ E \text{ is incorrect} \] Thus: \[ A,B,C,D \] \[ \therefore \text{Correct Answer is (D)} \]
