Question: Suppose that X, X2,... is a sequential sample from a N(0, 1) distribution, and that it is desired to test Ho: 0 =0 versus H:

Suppose that X₁, X2,... is a sequential sample from a N(0, 1) distribution, and that it is desired to test Ho: 0 =0 versus H₁: 0≠0. The experimenter reports that he used a proper stopping rule, and obtained the data 3, -1, 2, 1.
