Problem 1 In one state, 52% of the voters are Republicans, and 48% are Democrats. In a second state, 47% of the voters are Republicans, and 53% are Democrats. Suppose a simple random sample of 100 voters are surveyed from each state. What is the probability that the survey will show a greater percentage of Republican voters in the second state than in the first state? The solution involves four steps. This problem requires us to find the probability that p 1 is less than p 2. This is equivalent to finding the probability that p 1 - p 2 is less than zero. To find this probability, we need to transform the random variable p 1 - p 2 into a. That transformation appears below. Therefore, the probability that the survey will show a greater percentage of Republican voters in the second state than in the first state is 0.
