When doing Hypothesis Testing on Non-normal data Belts will use a ________________ to compare more than two sample proportions to each other.

Answer options

• A. Z score Table
• B. Sakami Table
• C. Mean-to-Mode Analysis
• D. Contingency Table

Correct answer: C

Explanation

The correct answer is C, Mean-to-Mode Analysis, which is specifically used for comparing more than two sample proportions in non-normal data scenarios. Options A, B, and D are not suitable for this purpose; Z score Table is for normal distribution, Sakami Table is not a recognized statistical method, and Contingency Table is primarily for categorical data analysis.
