Vaguely estimate the values of the z's you would next calculate (these are the variables which assign responsibility for points in the dataset to gaussians in the mixture, ie z5,1 is how must responsibility gaussian 1 has for point 5.)

Fill in the table of z values; points are numbered left to right; just get them vaguely right, ie the correct ordinal relationships and correctly close to 0 or 1 and suchlike.
