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 245 deaths among 34002 African miners and 7 deaths among 1503 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= 1.13 P-value - 0.13 Conclusion O There is significant evidence that the proportion of African miners who died is higher than the proportion of European miners who died. There is no evidence that the proportion of African miners who died is higher than the proportion of European miners who died.

rises and falls with the abundance of acoms, their favored food. Experimenters studied two similar forest areas in a year when the acorn crop failed. They added hundreds of thousands of acorns to one area to imitate an abundant acorn crop, while leaving the other area untouched. The next spring. 58 of the 75 mice trapped in the first area were in breeding condition, versus 10 of the 17 mice trapped in the second area. Give a 90% confidence interval for the difference between the proportion of mice ready to breed in good acorn years and bad acorn years.
