Confidence Intevral

[EL KIMON]

Dear all,
i need some help about CI. I am using bootstrap method and finding 95% CI ranges between ( 0.03 -0.08) and the coefficient is 0.06. That means that the estimate coefficient is significant because belongs to that range?
thank you.

El:
not quite.
It means that, in a series of repeated experiments, there's a 95% probability that the true, fixed and unknown value of the the population mean of the variable you're interested in ranges between 0.03 and 0.08.
Unless you're talking about the difference of two means (i.e., you're reporting the outcome of a bootstrap ttest), statistical significance is not an issue here.

I'd say that a strictly frequentist description here would indicate that "there's a 95% probability that *a confidence interval computed for the sample* includes the true, fixed and unknown value of the population mean of the variable you're interested in." (If the population mean is "fixed," I wouldn't say that it "ranges.") But, I'm fussy about such descriptions.

Mike:
yes "is included" sounds better than "ranges".
