The data on hospitalizations for swine flu, obtained in May 2009 from the Centers for Disease Control, is summarized in the accompanying table. The table looks at the relation between Age Group and Hospitalization, for all swine flu victims in the United States (www.cdc.gov).

Because some of the expected counts are less than 5, we should combine some groups. For this question, combine all the people who are 30 years old or older in one group and all the people who are less than 30 years old in another group. Show your new table.
Then test the new table to see whether there is an association between the variables, using a significance level of 0.05. Assume that this is a random sample from the population of all future and past swine flu victims.
