According to an article in Bloomberg Businessweek, New York
City's most recent adult smoking rate is 14%. Suppose that a survey
is conducted to determine this year’s rate. In a sample of 180
randomly chosen N.Y. City residents, 8.3% reply that they smoke.
Conduct a hypothesis test at the 5% level of significance to
determine if the rate of smoking has decreased. Include the
following steps in your test. • State the null and alternative
hypotheses • Calculate the test statistic • Find the p-value • Make
a decision whether to reject H0 • Write an interpretation of the
results.
