The following two-way frequency table summarizes the results of a study done on a random sample of 1000 high-school students. The students were asked questions about their smoking status as well as their parents’ smoking habits and classified accordingly: Can we conclude that the parental smoking status and student smoking behavior are independent? (a = 0.01). Show all the steps of a hypothesis testing problem. Write the expected frequency of each cell in the table above.
