In a certain city of several million people, 6.4% of the adults are unemployed. If a random sample of 255 adults in this city is selected, approximate the probability that at most 17 in the sample are unemployed. 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.

    0-75% of people live in the city and 25% live in the suburbs. we take a random sample of 1200 people. What is the probability that the number of these living in the suburbs is less than 270? This is a binomial distribution with a mean of 300 and a variance of 225. We can approximate by the normal distribution if we make a correction for continuity. In this case it means we use 269.5 instead of 270. Now use...
