International company claims that 45% of people in the U.S. support making cigarettes illegal within the next 5 to 10 years. You decide to test this claim and ask a random sample of 200 people in the U.S. whether they support making cigarettes illegal within the next 5 to 10 years. Of the 200 people, 49 % support this law. At a = 0.05, is there enough evidence to reject the claim? Verify that np > 5 and nq 2 5. Identify the claim. Then state the null and alternative hypotheses. Use the z – test. Sketch a graph. Interpret the decision in the context of the original claim.
