A.The sample mean always lies at the center of the confidence interval for the true population mean ( _X ).

B.The sample mean is also known as the best point estimate for _X .

C.As the sample size increases, the confidence interval becomes larger.

D.The true population mean is always in a 90% confidence interval for _X .

E.The true population mean is always in a 95% confidence interval for _X .

F.If one-hundred (100) 90% confidence intervals for _X are created from some population, the true population mean is likely to be in approximately 90 of these 100 confidence intervals.

If one-hundred (100) 95% confidence intervals for _X are created from some population, the true population mean is likely to be in approximately 95 of these 100 confidence intervals
