A 1. -11 points My Notes From the choices below, the statement that is **NO T* * true about confidence intervals is: A 900% confidence interval (CI) procedure has a higher probability of producing intervals that include the true population value than a 80% CI procedure. An approximate formula for a 90% confidence interval (CI) is: point estimate +/-bound A confidence interval (CI) between 0.15 and 0.35 means that the true population proportion lies between 0.15 and 0.35 A confidence interval (CI) is an interval of values computed from sample data that is likely to include the true, but unknown, population value 2. -11 points My Notes Suppose that a health expert has claimed that 16 % of college students smoke cigarettes. To investigate this claim , researchers survey a random sample of college students. Using this sample, a 99 % confidence interval for the percentage of college students who smoke is found to be 20.29 % to 23.71 %. Based this interval, can we conclude that the claim that 16 % of all college students smoke is reasonable? Select Select The claim of 16% is not reasonable because the value 16% is not in the confidence interval 3. The claim of 16% is reasonable because the value 16% is not in the confidence interval B My Notes The claim of 16% is not reasonable because the value % is in the confidence 16intervalley would fire their boss if they could . calculate a 95% confidence interval for the population proportion who The claim of 16% is reasonable because the value 16% is in the confidence interval to 3 pt each] Type here to search 2:15 PM 10/24/2017Explanation / Answer
2. Option A is correct because the confidence interval contains the values which are above 16% and hence,16% is not in the confidence interval.
