Suppose a polling agency reported that 44.1%of registered voters were in favor of raising income taxes to pay down the national debt. The agency states that results are based on telephone interviews with a random sample of 1047 registered voters. Suppose the agency states the margin of error for 99% confidence is 4.0%. Determine and interpret the confidence interval for the proportion of registered voters who are in favor of raising income taxes to pay down the national debt.
