Hi John,

Here is a suggestion for the wording:

(Under repeated Sampling) A confidence interval constructed in this way has a 95% probability of containing the true mean

Hope this helps.

Subject: 95% confidence interval: best description.

I would appreciate thoughts about the following two descriptions of a 95% CI:

Call

Send SMS

Call from mobile

Add to Skype

You'll need Skype CreditFree via Skype

For a given parameter X, a 95% CI round X is:

1) A range of values which we can say with 95% confidence contains the true value of the parameter.

2) A range of values constructed such that if an experiment is conducted 100 times, 95% of the time X will lie with the range.

I would welcome comments of the above descriptions, and any better descriptions that you might have.

Thank you,

John
