A survey was given to a random sample of 1450 residents of a town to determine whether they support a new plan to raise taxes in order to increase education spending. Of those surveyed, 48% of the people said they were in favor of the plan. Determine a 95% confidence interval for the percentage of people who favor the tax plan, rounding values to the nearest tenth.
