Problem #4: [2 marks] Marine biologists have noticed that the color of the outermost growth band on a clam tends to be related to the time of the year in which the clam dies. A biologist conducted a small investigation of whether this is true for the species Protothaca staminea. She collected a sample of 120 clam shells from this species and classified them according to the month that the clam died (February or March) and the color of the...

Smoking remains more common in much of Europe than in the United
States. In the United States, there is a strong relationship
between education and smoking: well-educated people are less likely
to smoke. Does a similar relationship hold in France? Here is a
two-way table of the level of education and smoking status
(nonsmoker, former smoker, moderate smoker, heavy smoker) of a
sample of 462 French men aged 20 to 60 years. The subjects are a

(1 point) A researcher is interested in whether the number of years of formal education is related to a person's decision to never smoke, continue to smoke, or quit smoking cigarettes. The data below represent the smoking status by level of education for residents of the United States 18 years or older from a random sample of 375 residents. Round all numeric answers to four decimal places. Smoking Status Education Level Current Former Never Less than high school 11 21...

1. A researcher is interested in the relationship between cigarette smoking and BMI (kg/m2) in adolescents. In order to test his hypothesis, the researcher decides to divide cigarette smoking into four groups based on the number of cigarettes smoked per day versus a control group of never smokers. The following incomplete ANOVA table summarizes a preliminary analysis for the difference in mean BMI for the groups. Sum of Squares df Mean Square Between Groups 54 Within Groups 38 Total 197...
