The Chi-square test of independence
Step-by-step explanation:
The answer to this question is the Chi-square test of independence because it is what is used to determine the existence of an association between nominal/categorical variables. This test is non parametric in nature and it can also be called the chi square test of association.
The data is tabulated. each row is a representation of the category for one of the variables and each column is for the other variable.
22.50-3.75= 18.75
18.75/1.25= 15
1.25 × X = total money left after purchases.
In expression form this is:
9 + 2f
