In function MRI study, we design a excitation sequence called paradigm, and test each brain voxel time sequence again the paradigm to compare their similarities. Assume the paradigm sequence is
{0, 0, 1, 1, 1, 0, 0, 0, 1, 1, 1, 0, 0}
and a voxel time sequence is
{0.1, -0.1, 0.9, 0.7, 1.1, 0.4, 0.5, 0.1, 1.2, 1.0, 0.9, 0.1, -0.1}
Calculate the t value of the t-test defined as
