ANSWER:
Solution 17BSC
We are given a data set between age groups and response or refusal to a survey. We have to test the claim that responding or refusing to a survey is independent of the age category.
Step 1: To test the claim we need to fulfil certain assumptions.
1. We assume that the sample has been randomly selected because of the structure of the study.
2. The results are tabulated as frequencies.
3. The expected frequencies are more than five in every column.
