Answer:
<em>Degrees of freedom for independence in chi-square statistic</em>
<em>ν = ( r-1) (s-1) =6</em>
Step-by-step explanation:
<u><em>Explanation</em></u><u>:-</u>
Given data chi-square test for independence is being used to evaluate the relationship between two variables
<em>Given "A" is classified into 3 categories</em>
<em>Second 'B' is classified into 4 categories</em>
In this chi-square test, we test if two attributes A and B under consideration are independent or not
We will assume that
<em>Null Hypothesis : H₀</em>: The two variables are independent
<em>Degrees of freedom in chi-square test for independence </em>
<em>ν = ( r-1) (s-1)</em>
<em>Given data 'r' = 3 and 's' = 4</em>
<em>Degrees of freedom for independence </em>
<em>ν = ( r-1) (s-1) = ( 3-1) ( 4-1) = 2×3 =6</em>
<em>Test statistic</em>
<em> χ ² = ∑ </em><em></em>

The solution to the problem expressed 2358.
<h3>What is the meaning of significant figure?</h3>Significant figure It is defined as the minimum number of digit us needed to express a number in scientific notation.
Therefore we get,
First we have to multiply the given digits as per rule.
Now we will add both the digits, we get
As per given expression, we conclude that the number of significant figure is 4.
So, the answer will be, 2358.
Therefore, the correct option is, 2358.
