During a presidential election year, many forecasts are made to determine how voters perceive a particular candidate. In a random sample of 120 registered voters in precinct X, 107 indicated that they supported the candidate in question. In an independent random sample of 141 registered voters in precinct Y, only 73 indicated support for the same candidate. The respective population proportions are denoted Px andPy. Find a 95% confidence interval for the population difference, (Px - Py).
