Chapter 9.4, Problem 1AC

Smoking and Education

You are researching the hypothesis that there is no difference in the percent of public school students who smoke and the percent of private school students who smoke. You find these results from a recent survey.

School	Percent who smoke
Public	32.3
Private	14.5

Based on these figures, answer the following questions.

1. What hypotheses would you use if you wanted to compare percentages of the public school students who smoke with the private school students who smoke?

2. What critical value(s) would you use?

3. What statistical test would you use to compare the two percentages?

4. What information would you need to complete the statistical test?

Suppose you found that 1000 randomly selected individuals in each group were surveyed. 5. Could you perform the statistical test?

6. If so, complete the test and summarize the results.
