A historian examining British colonial records for the Gold Coast in Africa suspects that the death rate was higher among African miners than among European miners. In the year 1936, there were 223 deaths among 34618 African miners and 7 deaths among 1509 European miners on the Gold Coast. Consider this year as a sample from the pre-war era in Africa. Is there good evidence that the proportion of African miners who died was higher than the proportion of European miners who died? Follow the Inference Toolbox. (Use a = .05.) Z = P-value = Conclusion O There is significant evidence that the proportion of African miners who died is higher than the proportion of European miners who died. O There is no evidence that the proportion of African miners who died is higher than the proportion of European miners who died.
