Question

Which of the following is a correct statement about a 90% confidence interval

A. If we repeatedly draw samples of the same size from the same population and construct confidence interval at the 90% confidence level using each sample mean, 90% of the resulting confidence intervals will include m.

B.There is a 90% probability that the population mean m will lie between the lower confidence limit (LCL) and the upper confidence limit (UCL).

C.We are 90% confident that our sample mean equals the population mean m.

D.90% of the population values will lie within the confidence interval.

C.We are 90% confident that our sample mean equals the population mean m.

Explanation / Answer

The confidence interval of values that covers the true population value for 90% of the samples selected.So, the answer is D

90% of the population values will lie within the confidence interval.
