Which kind of decision is it?
Tap a card, then tap its group.
Assumptions
•
A Type I error rejects a true H₀; a Type II error fails to reject a false H₀.
•
A test only ever rejects H₀ or fails to reject it; the truth about H₀ is unknown.
•
The chance of a Type I error is α, the significance level chosen before the test.
