Hi Everyone!
There is only 5 days left!
How's you guys study progress?

I got some statistic problems right now.
Could anybody explain "confident region VS Significant level"? "P-value VS Z-value"?

Why sometimes z-value =(observation - population mean) / sd; but sometimes z-value = (mean - population mean) / (sd / squared n)?

Thanks u guys!
And Good luck to all of you!
