Ok Grace, let's play a little game to see you can be helped to understand your error(s). Please just have a go :-) Lion, maybe you could have a play too? Shit, anyone that can be bothered, please play.
The game is: spot the null hypothesis. Below is a simple everyday situation, followed by several statements. One if them is clearly a null hypothesis, the others are clearly candidate H1s. Let's see what the consensus is:-
SITUATION: your car won't start.
HYPOTHESES:-
A) The battery is flat
B) There is a mechanical fault
C) The cause is as yet unknown
D) The car is out of fuel
E) The car is under a spell from garden pixies
Ok - let's play. Any thoughts?
