Question

In a certain city of several million people, 7.5% of the adults are unemployed. If a random sample of 220 adults in this city is selected, approximate the probability that at least 13 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.

Step 1

The mean of a binomial distribution is given by μ = np, where n is the sample size and p is the probability of success (in this case, being unemployed). μ = 220 * 0.075 = 16.5 The standard deviation of a binomial distribution is given by σ = sqrt(np(1-p)). σ = Show more…
