2. A random sample of subjects who tested positive for influenza during the 2014-15 flu season was obtained. The dataset is given in the Flu tab. There are four different influenza type: A/H1N1, A/H3N3, A-unsub, and B. There are five age groups. Each subject was classified by age group and influenza type. Determine whether there is evidence at the 5% significance level that age group and influenza type are associated. Fully justify! Include hypotheses, test used, needed assumptions, test statistic, p-value, decision and conclusion. HINT: you should put the frequencies into a matrix. Include the Observed and Expected Matrices in the report file.
