I am guessing that it is possible to reparameterize and rewrite Ho. Maybe Y_i/sigma=beta0+beta1*X+eps2_i

However, I still challenge you to actually do the calculations, say with mu=1/sqrt(5), sigma=1, for a few different values of N, and explain the results...if you can. Just for the record, in case someone ever wants to know the results, and since I already have them... Computations run
