To determine if topiramate is an effective treatment for alcohol dependence, researchers conducted a 14-week trial of 371 men and women aged 18 to 65 years diagnosed with alcohol dependence. In this doubleblind, randomized, placebo-controlled experiment, subjects were randomly given either 300 milligrams (mg) of topiramate (183 subjects) or a placebo (188 subjects) daily, along with a weekly compliance enhancement intervention. The variable used to determine the effectiveness of the treatment was self-reported percentage of heavy drinking days. Results indicated that topiramate was more effective than placebo at reducing the percentage of heavy drinking days. The researchers concluded that topiramate is a promising treatment for alcohol dependence. Complete parts (a) through (f).

What is the population for which this study applies? What is the sample.
1. the population is the 18-65 year olds with alcohol
dependence
2. the sample is 371 men and women aged 18-65 years diagnosed with
alcohol dependence
Why do you think it is necessary for the experiment to be double-blind?
so that way the subjects receiving the med do not behave differently and so the individual monitoring the subjects does not treat those receiving the medication differently than those receiving the placebo
