Which of these options provides the best interpretation of a 90% confidence interval estimate of the population mean ?
A) If we repeatedly draw samples of the same size from the same population, 90% of the values of the sample meanswill result in a confidence interval that includes the population mean.
B) There is a 90% probability that the population meanwill lie between the lower confidence limit (LC
L) and the upper confidence limit (UC
L).
C) We are 90% confident that we have selected a sample whose range of values does not contain the population mean.
D) We are 90% confident that 10% the values of the sample meanswill result in a confidence interval that includes the population mean.
