Bhai ap ne Question no 2(a) me Za/2=1.645 kese nikala ha. Aur formula me ap ne sath konsa symbol lgaya ha.Standard deviation ka ya aur  kyun? PLEASE explain this.

ahsan bhi yea a nhe blki alpha hea....

Ahsan Z alpha /2 ki value nikalna me ne question 1 k pasrt a me btaya hay detai l se usy follow karyn Thanks

hey brother Student's T-distribution ka table check karo then 0.05 kee infinte value check karo aapko aapka answer mil jaye ga try it hum ne estimation k chapter main se Z k table se value dekhni he nahi hai uski aik condition hai wo main khud likhu ga assignment main aap k liye yehi bht hai check kar lain

thankooooooooooooozzzzzzzzzz

Bhai zara Question no 1(a) me dekhay. is calculation me confusion ha

+2.06  in squre root  88+47/220  ye 6.75 k equal tu nahi ata. Zara calculate karey. Please

ahsan bhai solution again check karyn ghoor se

ahsan bhai sorry for intruption but brother i think aap k sab answers wrong hain???

Q1(a) confidence interval kaise nikaala aap ne?? aap ne likha hai "1minus alpha" = 0.96 am i right na,, but brother "we need 1st alpha then alpha by 2" alpha= 1 minus 0.96 = 0.04,   then we need alpha by 2 = 0.04 divided by 2 so "alpha by 2= 0.02" now 0.02 ko table main dekhna hai aur mere bhai jaan aap ne table value kaise nikaal lee?? jab k aapka answer 0.4800 hai aur jaise aap ne nikaali hai wahan 0.4803 aata hai am i right?? so there's a big difference bro. ,, u know what my brother table value Z table means area table se dekhni he nahi,, i think yeh aap bhi ache se jaante hain wo hum "T" table se dekhte hain just checked it

fox bhai it is standard k confidence interval ko 2 py divide karty hain then uski value Z table me dekhty hain its very simple. ap 1-aplha py mat jao wo alag kahani hay jo k next discussion me explain karu ga me

o mere pyaare bhai g , aap ne 1-alpha=0.96 likha hai, then phir us k neechay aap ne alpha by 2 pe yeh kyun likha 0.96/2???? mtlb ab aap ne alpha 0.96 liya jab k upar aap ne 1-aplha 0.96 liya hai ???? i think main aap se theek question kar raha hon but aap mere saare comments parhain agr dil kary tau reply karein ??? bcoz main tau apne points aap k through clear karwana chah raha hon k aap ne yeh kiya kaise ???? zara aap bhi apna solution aik baar ghor se dekhain my brother aapko point out nahi kar raha just apne points clear karna chah raha hon
