Just want to get some good memory.
Can you confirm what is the green horizontal line here?
And why the lines are shorter when the sample size is 10???
There are a lot of green horizontal lines in that image. Which one are you asking about?
Hi @Panda_Food
The green lines are confidence intervals around the sample mean estimates. Each line spans a range where we can be 95% confident that the true population mean falls within that interval, based on the given sample.
-
A larger sample size gives a more precise estimate of the population mean and reduced uncertainty.
-
The width of a confidence interval is inversely proportional to the square root of the sample size \sqrt{n}.
Hope it helps! Feel free to ask if you need further assistance.

I mean all the green lines - their definition. I think Alireza has reveals that. Thank you as well.
