Answer: We concluded that annual income and education level are not independent.
Step-by-step explanation:
For the given situation, the null and alternate hypothesis can be formulated as:
annual income and education level are independent.
annual income and education level are not independent.
Given, the value of test statistic is 24.32 and the critical value of test statistics is 13.32.

Therefore, we reject null hypothesis .
So , we concluded that annual income and education level are not independent.
