Can anyone verify this?

OpenStudy (vshiroky):

We are 95% sure that the true population falls between 2.26 and 4.34

OpenStudy (vshiroky):

@ganeshie8

OpenStudy (kropot72):

\[2.26<\mu<4.34\] On average, 95 out of every 100 such intervals will contain the population mean.

OpenStudy (vshiroky):

Was my answer correct then?

@kropot72

OpenStudy (kropot72):

Not really. Your statement "we are 95% sure" indicates the probability of the population mean being within the confidence interval. It is not correct to use probability in this context.

OpenStudy (vshiroky):

That's how my teacher told us to write confidence interval statements

OpenStudy (kropot72):

As I said, "95% sure" indicates probability. I prefer the more precise interpretation: On average, 95 out of every 100 such intervals will contain the population mean.

OpenStudy (kropot72):

If your teacher is happy with the use of "95% sure", go ahead and use it. I can't say it is incorrect.
