25% of adults say they would watch movies on their phone at work.

Consider this experiment a binomial.

Use normal approximation to the binomial to approximate the probability that between 50 and 80 adults (inclusive) in a random sample of 150 adults would say they watch movies on their phone at work.

    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.

    Example: According to a survey in a county, 28% of adults do not own a cell phone. Suppose a simple random sample of 200 adults is obtained Is the sampling distribution of normal? Why? What is the probability that in a random sample of 200 adults, more than 30% do not own a cell phone? Interpretation: If 100 random samples off 200 adults were obtained, one would expect 30% not owning a cell phone. to result in more than What...
