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 125 people from the city is taken, approximate the probability that fewer than 19 used an emergency room in the past year. Use the normal approximation to the binomial with a correction for continuity.

In 2001, 5.6% of people used cocaine. This year, a company wishes to use their employment drug screening to test a claim. They take a simple random sample of 2877 job applicants and find that 131 individuals fail the drug test for cocaine. They want to test the claim that the proportion of the population failing the test is lower than 5.6%. Use .05 for the significance level. Round to three decimal places where appropriate. Hypotheses: H o : p...
