Question

A comparative historical sociologist examining British colonial records for the Gold Coast in

Africa suspects that mortality was higher among African miners than European miners. In

the year 1936, there were 223 deaths among 33,809 African miners and 7 deaths among

1,541 European miners on the Gold Coast. (The Gold Coast became the independent

country of Ghana in 1957.) Consider data from the year 1936 as a random sample from the

colonial era. Did the proportion of African miners who died during the Colonial era differ

from the proportion of European miners who died?

1. State hypotheses in sentences and notation.
2. Calculate the pooled sample proportion.  
3. Compute the Z test statistic.
4. Estimate the p‐value that corresponds to the test statistic.
5. State your conclusion in reference to the null hypothesis. (Use α = .05)
6. Interpret your result in reference to the alternative hypothesis.
