An 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 33,809 African miners and 7 deaths among 1541 European miners in the Gold Coast. (Data courtesy of Raymond Dumett, Department of History, Purdue University.) Consider this year as a sample from the pre-war era in Africa. Do a significance test to test the claim that the proportion of African miners who died during a year was higher than the proportion of European miners who died. Use alpha=.05. Be sure to clearly define population 1 and population 2.
