Step-by-step explanation:
The chi square test of independence is used to determine if there is a significant association between two categorical variables from a population.
It tests the claim that the row and column variables are independent of each other.
The degrees of freedom for the chi-square are calculated using the following formula: df = (r-1) (c-1) where r is the number of rows and c is the number of columns.

Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Required
Interpret p(4)
This implies that c = 4
Substitute 4 for c in
There are no option attached to this question.
<em>I'll assume c represents cost and p(c) represents the profit.</em>
<em>Base on this assumption, a suitable statement is:</em>
<em>When cost is 4, the profit is 5360.</em>
I can solve it with substitution and elimination but not linear combination
