t distribution??
If U and V are independent, U being distributed N(3,16) and V being distributed as chi-square on 9 degrees of freedom, find
P(U-3 < 4.33 sqrtV).
Well I don't even know where to start! Does U-3 suggest the mean is 0? Is the whole distribution of U shifted left by 3? Does that give a t distribution?
I am not asking for the answer but some direction would be appreciated, I just can't seem to understand this at all.
