6.4.10. In a study of factors thought to be responsible for the adverse effects of smoking on human reproduction, cadmium level determinations (nanograms per gram) were made on placenta tissue of a sample of 14 mothers who were smokers and an independent random sample of 18 nonsmoking mothers. The results were as follows: Nonsmokers: 10.0.8.4. 12.8, 25.0, 11.8.9.8. 12.5, 15.4.23.5, 9.4. 25.1, 19.5. 25.5.9.8. 7.5, 11.8, 12.2, 15.0 Smokers: 30.0, 30.1, 15.0, 24.1, 30.5, 17.8, 16.8, 14.8, 13.4, 28.5, 17.5, 14.4, 12.5, 20.4 Does it appear likely that the mean cadmium level is higher among smokers than nonsmokers? Why do you reach this conclusion?

Question

Transcribed Image Text:6.4.10. In a study of factors thought to be
responsible for the adverse effects of smoking on
human reproduction, cadmium level
determinations (nanograms per gram) were
made on placenta tissue of a
sample of 14 mothers who were smokers and an
independent random sample of 18 nonsmoking
mothers. The results were as follows:
Nonsmokers: 10.0.8.4. 12.8, 25.0, 11.8.9.8. 12.5,
15.4.23.5, 9.4. 25.1, 19.5. 25.5.9.8. 7.5, 11.8, 12.2,
15.0 Smokers: 30.0, 30.1, 15.0, 24.1, 30.5, 17.8,
16.8, 14.8, 13.4, 28.5, 17.5, 14.4, 12.5, 20.4 Does it
appear likely that the mean cadmium level is
higher among smokers than nonsmokers? Why
do you reach this conclusion?
