Political polls typically sample randomly from the U.Spopulation to investigate

Political polls typically sample randomly from the U.Spopulation to investigate the percentage of voters who favorsomecandidate or issue. The number of people polled isusually on the order of 1000.Suppose that one such poll asksvoters how they feel about the Presidents handling of the crisisin the financial markets. The results show that 575 outof the1280 people polled say they either approve or strongly approveof thePresidents handling of this matter. Based on thesample referenced above finda 95% confidence intervalestimate for the proportion of the entire voterpopulation whoapprove or strongly approve of the Presidents handlingofthe crisis in the financial markets.Now heres an interesting twist. If the same sample proportion wasfound in a sample twice as largethat is 1150out of 2560howwould this affect the confidence interval?
