The results of the National Health and Nutrition Examination Survey for the year 2011-12 found that 12.9% of the adults of age 20 and more in the United States had high total cholesterol. Assume that a researcher surveys a sample size of 120 for above 20 years. Construct a 95% confidence interval estimate for the population proportion so that the cholesterol level is the same as 12.9% (PHStat). Assume that a researcher surveys a sample size of 1,200 for more than 20 years. Construct a 95% confidence interval estimate for the population proportion so that the cholesterol level is the same as 12.9%.(PHStat) Compare the results in (a) and (b).
