- Of 102 randomly selected adults, 42 were found to have high blood pressure. A 90% confidence interval for the true percentage of all adults that have high blood pressure is . What is the value of ? (Round to two decimal places).In a random sample of 250 high school students, it was found that 85.2% (213) of them later graduated. Find the 95% and 98% confidence interval for the true proportion of all high school students who graduate. Compare the two proportions.Find the margin of error for the 99% confidence interval used to estimate the population proportion. In a clinical test with 1100 subjects, 25% showed improvement from the treatment.
- National statistics show that 23% of men (sample 1) smoke and 18.5% of women (sample 2) do. A random sample of 149 men indicated that 64 were smokers , and of 119 women surveyed , 41 indicated that they smoked.
