A brokerage survey reports that 39% of all individual investors have used a discount broker. If a random sample of 145 investors is taken, approximate that probability that 55 have used a discount broker. Use the normal approximation to the binomial with a correction for continuity. Round your answer to three places, do not round intermediate steps.
