Teenagers Who Smoke Different Cigarette Brands, Marlboro Smokers

Next, responses to the following question were analyzed: "How much interest would you have in participating in a stop-smoking program that was designed for people your own age?" Response categories were great deal of interest, some interest, little interest, and no interest at all.

A comparison of the response rates of Marlboro and Newport smokers yielded a chi-square statistic of 5.019 with a p value of .170. Thus, at a 5% significance level, the two groups did not differ. With responses coded 1 for great interest, 2 for some interest, 3 for little interest, and 4 for no interest, the mean score for Marlboro smokers was 2.81, while the mean score for Newport smokers was 2.70. This indicates that, on average, Marlboro smokers were slightly (but not significantly) less interested in a peer stop-smoking program.

Comparing the responses of Camel and Newport smokers resulted in a chi-square statistic of 9.70 with a p value of .021. Thus, their responses were significantly different at the 3% level. The mean score for Camel smokers was 3.31, which exceeded the mean score for Newport smokers (2.70). It appears that the Camel smokers were far less interested in a peer stop-smoking program than were Newport smokers.

The comparison of Marlboro and Camel smokers yielded a chi-square of 9.12 with a p value of .028. Their responses were significantly different at a 3% significance level, with the average Camel smoker less interested in a peer stop-smoking program as compared with the average Marlboro smoker.

Finally, responses to the following question were examined: "All things considered, would you like to give up smoking?" Response categories were yes, no, and do not know.

A comparison of the response rates of Marlboro and Newport smokers resulted in a chi-square of 2.60 with a p value of .107. At a 5% level of significance, their responses were not different. There were similar results for the remaining two comparisons. That is, the response rates of Camel and Newport smokers and Camel and Marlboro smokers were not significantly different.
