swine nu The data on hospitalizations for swine flu are summarized in the accompanying table. The table looks at the relation between Age Group and Hospitalization, 1 country. Because some of the expected values are less than 5, some groups should be combined. Combine all the people who are 30 years old or older in one group and all the people 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 a = 0.05.

↑ The data on hospitalizations for swine flu are summarized in the accompanying table. The table looks at the relation between Age Group and Hospitalization, for all swine flu victims in a certain country. Because some of the expected values are less than 5, some groups should be combined. 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 a = 0.05. Assume that this is a random sample from the population of all future and past swine flu victims. Click the icon to view the swine flu hospitalization data. Complete the table. Hospitalized, Yes Hospitalized, No Totals Age Group Under 30 30 and Over Totals 54 557 611 Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: There is an association between age group and swine flu hospitalization. Ha: There is no association between age group and swine flu hospitalization. OB. Ho: There is no association between age group and swine flu hospitalization. Ha: There is an association between age group and swine flu hospitalization. OC. Ho: There is no association between age group and swine flu hospitalization. Ha: There is a positive association between age group and swine flu hospitalization. O D. Ho: There is no association between age group and swine flu hospitalization. H₂: There is a negative association between age group and swine flu hospitalization.
