Most recent tests and calculations estimate at the $95 \%$ confidence level that mitochondrial Eve, the maternal ancestor to all living humans, lived $138,000 \pm 18,$ ooo years ago. What is meant by "95\% confidence" in this context?
(A) A confidence interval of the true age of mitochondrial Eve has been calculated using $z$ -scores of ±1.96 .
(B) A confidence interval of the true age of mitochondrial Eve has been calculated using $t$ -scores consistent with $d f$ $=n-1$ and tail probabilities of $\pm 0.025 .$
(C) There is a 0.95 probability that mitochondrial Eve lived between 120,000 and 156,000 years ago.
(D) If 20 random samples of data are obtained by this method and a $95 \%$ confidence interval is calculated from each, the true age of mitochondrial Eve will be in 19 of these intervals.
(E) Of all random samples of data obtained by this method, $95 \%$ will yield intervals that capture the true age of mitochondrial Eve.
