comment Showing That Two Normal-Based Random Variables Have the Same Distribution
That's correct.

comment Showing That Two Normal-Based Random Variables Have the Same Distribution
Two hints 1) The second term of each pair follows a Chi square distribution witn $n-1$ degree of freedom 2) it seems to me that even if you demostrante that, that would be not enough, because you need to show that the joint distribution is the same (not merely each of them, i.e., the marginals)

comment Does there exist a non-negative valued compactly supported function such that its Fourier transform only vanishes at a given point?
Well, the Fourier transform of a real-valued function is hermitian, so I think you should at least have $\widehat f(-t_0)=0$ too

comment Counting bit strings of length 10 contain either 5 consecutive 0's or 5 consecutive 1's
As I said, $k$ is the position of the first zero in the run (sequence of consecutive 5 or more zeroes)

comment Kullback-Leiber divergence for two simple probability vectors
I don't understand what "probability vectors... representing monotonically increasing functions" mean.
