A recent study was conducted involving 60 men who drink >=3 servings of alcohol on most days; we will refer these men as "heavy drinkers," or "hd." Their sample average serum cholesterol was (xbar=) 210 mg/dL. The 95% CI for the true population serum cholesterol in this population of heavy drinkers (=mu hd =hd) was (187 mg/dL, 233 mg/dL).

Which of the following would be the best interpretation of the 95% CI?
