Thankyou So much Sir Aapke karan Yeh topic clear ho gya...🙏🙏🙏🙏💯
Welcome dear
agar aap ko samaj aa gaya toh mere ko bhi samj aa jaiga
Haan Bhai.. Bilkul Samaj Aa Jaega...Sir Ne Bht Aache se Samjhaya Hain..
sir, please upload lectures on anova concepts of this unit.
Yes dear
Sir isme last question jo aapne karaya usme t ki value galat nikli hai and also t0.05 bhi aapne 0.10 wala column dekh liya sir
Ohh
Correct it
T-9.39?
Yaah I got 9.72 @@ShankarAnil-vl6cq
Sir first question m s k liye aapne 10+14-1 glat liya h
10 + 14 -2 hona h jo ki sahi h
Please correction kijiye agar sahi h toh
Sir last Q mai |t| = 9.41 aa ra h and aapne t alpha 0.1 se kra h blki .05 se krna tha toh yeh case rejected hoga kyoki value
|t|>t alpha
|t|= 9.41>t alpha=2.160
Ok
sir sailor me accept hone pe aapne kaha ki salor ki height jyada hai lekin last question me reject hone pe aapne kaha ki type 1 jyada accha hai aisa kyu
accept hone ka toh matlab mean equal hai. aur mean he toh average height hai na toh mean equal hone pe sailors ki average height jyada kyu aayi equal aani chahiye thi na.
Sabhi question same nhi hote
Sabme null hypothesis different aayega question ke according
Sir aapse padh kar bahut maja aa rha thanku so much
Welcome dear
At 34:40 can you please confirm if the final statement is correct or not i.e. sailors are on average talller than soldiers is true .
True
wonderful explain thanku sir
Welcome dear ❤❤
Sir second last question mein jab dono ka mean same hai to sailors taller kaise hue soldiers se? Not taller hona chahiye na?
Dear sample size bhi dekho
sir ab bhi samjh ni aaya@@dr.anuj.fearlessinnocentmath
sir at the end 40:07 t(0.05) value in table not 1.77 its 2.160
Ok dear
38:39 Sir, you forgot to root
(1/8+1/7)
sir if mean of sailors and soldier mean is same how we can say that on average sailor are taller then soldier
Did you find out the answer yet?
@@jomainaahmed did you got the ans? 😅
@@Hejehh83nsbjwk73 Normal average formula lga lo sailor/soldier ki height ka sum divide by no. of sailor/soldier.
