B) For the variables X and Y, the equation of regression line is 4x-5y+33 = 0 and 20x- 9y =107. Identify the regression lines. Find co-relation co-efficient, X¯, Y¯ and oy. If variance of x is 9.
7. Given the two equations for regression lines : 8x - 10 y + 66=0 40x - 18 y- 214=0 (i) Identify the regression lines of Y on X and X on Y. (ii) Obtain regression coefficients and the correlation coefficient . (iii) Find the mean of X and the mean of Y (iv) Given the standard deviation of X =4 , find the variance of Y.
@@triparnasarkar8633 lol its just a simple root of both line you just need to solve both equation with any method then you will geet values pf x and y
Both of equations give only one value not two if he assumed x on y And y on x it's not a best approach to solve that type of questions, you can watch another video
Plzz tell me the answer question is , If the correlation coefficient between the two Variables X and Y is 0.4.then the correlation coefficient between X+3 and Y-5 is _________? Plzz answer me🙏
Y calculating in calculator.... I want to knw how to find the X n Y
Nigga do it manually 🔪

Sir iska answer milega
Thanks Sir.. 😀
You Clear My Dout.. 👍
You made my day. Thanks friend.
Amazing u explained well and it seemed easy thankyou so much liked😃
Ajj mera viva tha.. Tunhare ye video na bacha liya mereko m ❤️❤️
College main 1 hour ka lecture or calculations ke bad vi nahi samaj aya lakin yr 15 min ka ye video..... 👌wah sachmain kamal ki ho up sir 🙏🏼

last part variance wala kese hoga

Its may helps
Bahut aacha bataya h aapne thanku
Thank you
Thank u so much.
Very good explanation
Thank you sir
Helpful 👍
Thankyou sir
How did you calculated 3&0.5 while using calculator
That's my question also... Everyone doesn't have this calculator...
@@triparnasarkar8633 Use Casio Fx-991ES calculator or you can solve it by option Mode and then Equation 👍
@@triparnasarkar8633 lol its just a simple root of both line you just need to solve both equation with any method then you will geet values pf x and y
Okkkk.... Thank you😐
caymars rule
if var x =3 ; find standard deviation of y?
ye part kese krenge
If bxy or byx is positive and another is negative then
Plzzzz answer
Both of equations give only one value not two if he assumed x on y
And y on x it's not a best approach to solve that type of questions, you can watch another video
Can you tell me how you find the mean value of X and Y .
Using calculator
If the equation of the regression line is y=-03x0.4, then the correlation coefficient between the two variables will beً??( positive or negative)
Plzz tell me the answer question is ,
If the correlation coefficient between the two Variables X and Y is 0.4.then the correlation coefficient between X+3 and Y-5 is _________? Plzz answer me🙏
sir isa mehod se marks milaga na
\
Sir mere example mai 1 equation mai value 1 se choti hai hi nhi fir kya kare
r ka answer positive hai sir
Kal exam he abhi so jata hu 😂
Aise kehkr top krne waalon ko hum hi*ade kehte hai
If the correlation coefficient between the variables X and Y is r , the correlation coefficient between X^2 and Y^2 is *
I didn't understand on calculator
Please can u do the calculation on paper
Sample means x bar aur y bar kaise calculator mein nikala samjha nhi
Can you tell me the answer
3x+2y-26=0 and 6x+y-31=0
What is the r value say me I did
Under root Mai 1 value ( -) Aa gayi to kya karne ka?
Is r can be greater than 1
Sir mere pass calcuter nhi hai o bata de plz sir
Sir Agar Sirf Correlation Coefficient Nikalne Keliye kaha toh Kya karne Ka ?
Sir mean hi smjh me nai aayi kese calculate kia apne
bro breathes with a calculator
Your rule didnt work for my question ??
x &y bar ka value kaise nikale samajh nhi aaya bhai
Sir what is the sign of r if Bxy is -ve and Byx is +ve
-
1 se kam hi chahiye kya?
Please dont do in calculator bcz of that how can we write in exam do practically and show please
Bahut confuse kar diya bro
Mast calculator use krta hai yeh
Sir 1st step nhi samaj ayi plz sir bataye
Can value of r be greater than 1?
Never
worst video bhai shi se toh bata calculator se krna hota toh teri video kyu dekhte
byx= -0.167
Listen carefully what I told in video
+ Or - doesn't matter while checking for
Wrong
Thank you sir
