QUESTION 242

A researcher reports an observed 95% confidence interval (8,12) for a fixed population mean. Which interpretation is valid?
(A)
The procedure captures the fixed mean in about 95 percent of repeated random samples.
(B)
Exactly 95 percent of individual observations lie between 8 and 12.
(C)
Exactly 95 percent of future sample means lie between 8 and 12.
(D)
The fixed mean now has probability 0.95 of lying between 8 and 12.
