Explanation:
Detailed explanation-1: -We use the chi-square (2 ) test to assess the null hypothesis of no relationship between the two categorical variables of a two-way table. To test this hypothesis, we compare actual counts from the sample data with expected counts, given the null hypothesis of no relationship.
Detailed explanation-2: -The hypotheses for a Chi-square test of independence are as follows: Null Hypothesis (Ho): There is no association between the two categorical variables in the population of interest. Alternative Hypothesis (Ha): There is no association between the two categorical variables in the population of interest.
