原文标题:Inference about the Difference Between Two Population Proportions
题目是这样的....
In a recent survey of gun centrol laws, a random sample of 1000 women
showed that 65% were in favor of stricter gun control laws. In a random
sample of 1000 men, 60% favored stricter gun control laws.
Test the claim that the percentage of men and women favoring stricter
gun control laws in the same. Use a=0.05 (a=阿法)
自己本身英文不好，不过有努力查过单字大致上知道它的意思

希望有高手可以救救我~
