 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)  "I don't ride side-saddle. I'm as straight as a submarine"

 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.

Mine is blank. It would be great help if you can paste it here. Thanks.
