I had the same problem clearing my graph. When I wanted to use the normal y= function it still had the Z-Test Plot.

How I cleared it was I pressed y= (top left button on Ti-84) typed sin(X) in the first Y function so it looks like  "\Y1=sin(X)"

Then I pressed the STAT button,  > (right button), > (right button), TESTS, Z-Test... and clicked Draw again,

And before it finished graphing the y=sin(x) function I really quickly pressed 2nd ON,

Then is says "ERR: BREAK 1: Quit"

I press enter

And now when I go back to my graph it only displays sin(x), the Z-Test Plot has been cleared! hooray!

With all the math you know is time to make some money and get yourself a few classes to fix  your accent because it gets annoying after a while. This video is not clear enough.
