Question details

23. A poll of 250 people shows the supporting rates of two candidates of the state congress: - candidate A: 28.3%±3%; candidate B: 32.1%±3%. Do we conclude that candidate B’s supporting rate is higher than candidate A (or can we reject the hypothesis that the two candidates’ supporting rates are same)? Why? What if the supporting rates of a poll are 28.5%±2% for A and 32.7%±2% for B? Why?
