Three national news networks are trying to estimate what percentage of American voters support a particular presidential candidate. To estimate the
population parameter, each of the three networks collects data from a simple
random sample of voters. Here are the numbers of voters in the networks'
random samples:
• Network A: 2250 voters sampled
• Network B: 2800 voters sampled
• Network C: 2500 voters sampled
