Does confidence really mean the percentage of confidence allocated to the question?

Because in my textbook, it tells us that the confidence interval tells us that simply 95% of the sample mean values will within the confidence interval in terms of the population mean.

There is no "trust" or "confidence" really invested, is there?

Hey- I want to express my gratitude for your excellent explanation of these statistics concepts. I find them very easy to understand. I took graduate stats class. I’m not sure i got those concepts beyond reasonable doubt.

Thanks for using a great teaching tool-great graphs, formulas, examples. I admire your ability to spots and explain the concepts that give hard time.
