**Options Explained for Educational Assessment Evaluation**This image presents three different options related to scoring on a test consisting of 30 questions:a. **At least 20 out of 30 correctly:** This option indicates a minimum threshold of 20 correct answers. Any score achieving 20 or more correct answers falls into this category.b. **Exactly 25 out of 30 correctly:** This choice specifies a precise score of 25 correct answers. It is not a range, but rather a fixed number of correctly answered questions.c. **Exactly 25 out of 30 wrong answers:** This is a unique scenario where 25 questions are answered incorrectly, thereby implying that 5 questions were answered correctly.These options may be used to assess different achievement levels or scenarios in educational testing.

Concept explainers

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
