Suppose that 14% of the people in a large city have used a hospital emergency room in the past year. If a random sample of 155 people from the oty is taken, approximate the probability that at most 22 used an emergency room in the past year. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (4f necessary, consult a liat of formulas.)
