is there a question u have been working on ?

ganeshie8 · Answer

u can think of confidence interval as "fish net" that catches the population parameter, living in sample environment

ganeshie8 · Answer

using just the "mean" is like catching fishes with an "arrow".

using "confidence interval" is like catching fishes with a "net" --- u will have great chances when u go for catching with net compared to just a "bow and arrow"
