Nicotine in Filtered Cigarettes
Use the frequency distribution from Exercise 20 in Section 2-2 to construct a histogram. Compare this histogram to the histogram from Exercise 11.
Exercise 11:
Comparing Relative Frequencies
Construct one table (similar to Table 2-8 on page 51) that includes relative frequencies based on the frequency distributions from Exercises 5 and 6, then compare the amounts of tar in non-filtered and filtered cigarettes. Do the cigarette filters appear to be effective?

Exercise 20:
Nicotine in Filtered Cigarettes
Refer to Data Set 4 in Appendix B and use the 25 nicotine amounts (in mg) listed for the filtered and non-menthol cigarettes. Construct a frequency distribution. Begin with a lower class limit of 0.2 mg, and use a class width of 0.20 mg. Compare the frequency distribution to the result from Exercise 19.
Exercise 19:
Nicotine in Non-filtered Cigarettes
Refer to Data Set 4 in Appendix B and use the 25 nicotine amounts (in mg) listed for the non-filtered king-size cigarettes. Construct a frequency distribution. Begin with a lower class limit of 1.0 mg, and use a class width of 0.20 mg.
Data Set 4: Cigarette Tar, Nicotine, and Carbon Monoxide
All measurements are in milligrams per cigarette. CO denotes carbon monoxide. The king size cigarettes are non-filtered, non-menthol, and non-light. The menthol cigarettes are 100 mm long, filtered, and non-light. The cigarettes in the third group are 100 mm long, filtered, non-menthol, and non-light. Data are from the Federal Trade Commission.
