I've been posed the following question:
Initially, I tried approaching this question by applying a 'comparing proportions' test on the information given. However, there is insufficient information; I cannot calculate the test statistic because the successes and sample size for global influenza is not given. Should I approach this question with null hypothesis: $H_0 = \mathrm{mean}(\text{oceania}) = \mathrm{mean}(\text{global})$ ?
