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.

**Task: Calculate the F-test Statistic**
Objective: Find the F-test statistic to assess the claim that the variances of two populations are equal. Both distributions are assumed to be normal, and the populations are independent.
**Information Provided:**
- Standard deviation of the first sample: 9.0161
- Standard deviation of the second sample: 9.6012
Instructions: Compute the F-test statistic using the provided standard deviations.

We have to find the F test statistic to test the claim that the variances of the two populations are equal.
Both distributions are normal.
The populations are different.
The standard deviations of the samples are 9.0161 and 9.6012 respectively.
