Question

From the choices below, the statement that is **NOT** true about confidence intervals is:

A confidence interval (CI) is an interval of values computed from sample data that is likely to include the true, but unknown, population valueA confidence interval (CI) between 20.00 and 39.00 means that the true population average lies between 20.00 and 39.00    An approximate formula for a 90% confidence interval (CI) is: point estimate ± boundA 90% confidence interval (CI) procedure has a higher probability of producing intervals that include the true population value than a 80% CI procedure.

Explanation / Answer

The statement that is NOT true is : A confidence interval between 20.00 an 39.00 means that the true population avergae lies between 20.00 and 39.00.

it is not true because it must state "a likelihood of (1 - alpha)% is that" the true population proportion lies between between 20 and 39.
