Friends, I just want to know if there is an issue with the solution to Q. 6.10 in Chapter 6. While considering the mean and variance in 1000's, I think in the solution, variance is wrongly considered as 10 & 5 ofr x & y respectively. Don't u think, variance should be computed as (10000x10000)/10x1000 for variance of x and (5000x5000)/10x1000 for variance of Y?
I feel either the answer is incorrect or in the question the word "standard deviation"should be replaced by "Variance".
