Omega-3, revisited Exercises 21 and 35 describe an experiment investigating a dietary approach to treating bipolar disorder. Researchers randomly assigned 30 subjects to two treatment groups, one group taking a high dose of omega-3 fats and the other a placebo.

a) Why was it important to randomize in assigning the subjects to the two groups?
b) What would be the advantages and disadvantages of using 100 subjects instead of 30?

Green Tea and Prostate Cancer A preliminary study suggests a benefit from green tea for those at risk of prostate cancer. The study involved 60 men with PIN lesions, some of which turn into prostate cancer. Half the men, randomly determined, were given 600 mg a day of a green tea extract while the other half were given a placebo. The study was double-blind, and the results after one year are shown in the table below. Treatment Cancer No Cancer Green Tea 1 29 Placebo 9 21 (a) Test at a 5% significant level to see if the sample provide evidence that taking green tea extract reduces the risk of developing prostate cancer. (b) Find 98% confidence interval for the difference between two population proportions of men with PIN lesions who get prostate cancer after taking green tea extract and after taking placebo for a year. Interpret the C.I. result.

In a study recently published in a health journal, it was suggested that lack of exercise contributed more to weight gain than eating too much. The study examined the current exercise habits and caloric intake of a sample of both males and females. Was this an observational study or an experimental study? Explain why. O This is an experimental study because the researchers randomly assign treatments to the subjects and observe the outcomes on the response variable, weight gain. O This is an observational study because the researchers randomly assign treatments to the subjects and observe the outcomes on the response variable, weight gain. O This is an observational study because the researchers did not assign treatments to the subjects. The researchers observed the current habits of the subjects. O This is an experimental study because the researchers did not assign treatments to the subjects. The researchers observed the current habits of the subjects.

Cocaine addiction is very hard to break. Even among addicts trying hard to break the addiction, relapse is common. (A relapse is when a person trying to break out of the addiction fails and uses cocaine again.) A study is conducted to investigate the effectiveness of two drugs, desipramine and lithium, in the treatment of cocaine addiction. The subjects in the six-week study were cocaine addicts seeking treatment. The 72 subjects were randomly assigned to one of three groups (desipramine, lithium, or a placebo, with 24 subjects in each group) and the study was double-blind. Relapse No relapse Desipramine 10 14 Lithium 18 6 Placebo 20 4 1.We are interested in knowing whether there was a difference in the proportion of relapse between the two drugs.
