This is considerably more straight forward than what I was taught. Thanks!
Excellent! Straight forward to the point. Thank you
Very quick video and liked it a lot. no lagging only solving.
Quite elaborate and easy to understand. Good job.
Thanks so much .plz upload more numerical problems.we are gating more benefits by your great efforts.
Thanks for your contribution.
thank you.. have learnt so much. please do more videos on conditional mean and variance of multivariate distribution given mean vector and covariance matrix.
Thanks. Can you please tell why haven't you divided by square root of n to normilize?
Your Video was super helpful. Thanks
very helpful--thank you!
great video, thanks a lot!
Thank you!
Thank u so muchhh... Really helping me
wow amazing video!
Thanks a lot sister. Very helpful tutorial.
Finally a tutorial that doesnt teach me like a 3rd grader
Good work done. kindly, solve more questions on mv data analysis your videos are very helpful.
Thank you...
Thank you. Also, where is c?
Great!
thank you
Very nice explanation mam
Very helpful
3:36 she said it. she said mewtwo!
Gotta catch em all!
I guess I fell in love to your relaxing voice.
Why u can't discuss its expectation value and variance?? I didn't see any video which briefly discuss other parameters in their example.
wow
How to get .3085??
you can use a calculator to get it. go-to mode then 3, go-to AC shift+1 then, press 5 then 1 then you enter the negative. p(-0.5)=0.30854. yes, this is how you get the value. So, if it is already a less-than probability, just enter the value without negating it. thank you

Probabilities are killing me with improbable certainty...
Great video...Just please do not use that eraser many times!
The probability that statistics is a bit over my head =1 🥺
A mistake was done in your calculation on the multiplication of the first matrix one at row one column three with matrix two at row 2 column 3 the answer of the multiplication should be 10 you had six.
why is p(z-0.5)?
thats the only confusion I've come across in the entire video...
It is because of symmetry that from -inf to -0.5 is equal in are to 0.5 to +inf
@@Jayveersinh_Raj got it, thanks
I think the answer for part (a) should be 0.8085 and not 0.3085 because it's
1- P(z>0.5)= 1- 0.1915= 0.8085.
Is this correct?
no it's 1-0.69
She looked up the value to infinite CDF output indirectly by a negative, but if you don't have a CDF table that has negative z values, or if you are using something like Matlab's normcdf function, it is going from negative infinite to the value. In this case that is a cumulative probability of 0.69, which is the probability that the value is < 6, thus for > 6 you can take 1 (the sum total probability) - 0.69, which is the probability left over, aka, > 6. This makes the final answer ~ 0.31. May also want to check how you got 0.1915, as it does not equal that for 0.5 either summation direction.
@Juma Ciry....because she used the negative when you pick your calculator, go-to mode then 3, go-to AC shift+1 then, press 5 then 1 then you enter the negative. p(-0.5)=0.30854. yes, this is how you get the value. So, if it is already a less-than probability, just enter the value without negating it. thank you
There is a mistake it should be 20Cov(X2,X3), 5*4=20
Her voice is just gorgeous, healing my heart broken by the god damn mathematics
literally every girl has this voice
