Question 3 anyone?

[Granpa Simpson]

[rongmon]

Thanks Subhayu, great help.

[rongmon]

Can you elaborate how you went forward from the second last step - 1/2 - 1/3 + 1/4 ...

Thanks

[Granpa Simpson]

Using expansion of log(x+1) we get, log 2=(1-1/2+1/3-1/4+..........
1-log2= 1-(1-1/2+1/3-1/4+.........
        = 1/2-1/3+1/4-1/5.........which is equivalent to (1)

[rongmon]

Got it!

someone please share solution to Q.26

 In an analysis of bivariate data (X and Y) the following results
were obtained. Variance of  X = 9 ,  product of the regression coefficient of Y
on X and X on Y is 0.36, and the regression coefficient from the
regression of Y on X is 0.8
The variance of Y is

[Cermank]

Given that b(xy) * b (yx) = 0.36

b(yx) = 0.8.

b(yx) = cov(x,y)/var(x) => 0.8 = cov(x,y)/9 => covariance is 7.2

b(xy) = 9/20 = 7.2/var(y) and we solve for y.

Hi everyone. I am really sorry that this question is out of context of the ongoing discussion but can any one of you share the instructions from the instructions booklet which was there on the page from where we downloaded our ISI admit cards. Mine is blank. It would be great help if you can paste it here.

Thanks.
